I am not really sure what you are asking. In that painful process i damaged multiple Arduino mainly before doing the opti coupler interface. Save money on your purchases by earning redeemable points with Progressive Rewards! I've been using my Raspberry Pi in this case that I 3D printed almost two years ago. I also changed the delay times so as not to burn up the actuator motor as rapid on off will do that. 0000022822 00000 n

Thank you for your reply. There is a continuing push for higher force but at lower costs. 44 35
I can only describe to you what I have found to help me solve my problems. As for why, because theyre open source and widely supported online. I changed to 550 nothing! Thank you for the reply. No wonder why because it is hard as hell and expensive to do the real thing!!!!! Hi Albert, 0000003721 00000 n
that depends on what you have the reverse light setting at. elero, the name which stands for high-quality electric precision linear actuators. Is there any reason why you use an additional battery instead of the storage battery to power your Arduino? 78 0 obj

Fisheye, mounting holes, any clevis type, trunnions, or custom designed solutions are available. Display the readings from your analogue inputs to your Arduino IDE Serial Monitor, they should be values between 0 and 1023. b/ no limit switch for safety cut off. What it does: inseguitore Once i know that it is simply a matter of checking to see if code is working as written. Your existing code does not work! Hi James. In the search, I also found the article https://12vactuators.com/solar-tracker-with-linear-actuator/. Hi Adam, Hi, my name is Michael and I started this blog in 2016 to share my DIY journey with you. Go read the long reply i sent to Albert. I would advise you to learn how to use the monitor so you can make the correct corrections and insure your power lead to the sensors is plugged into the 3.5v connection. xref
actuator linear electric 12v dc rc 24v tracker robotics stroke robot solar gone almost This way we can define limits for the starting position 0, and ending position 180, of the tracker. There is no such thing as focus on 1 LDR. If you do too, grab a cup of coffee and settle in, I'm happy to have you here. Yes this exact problem kept happening and I could not figure out why. Yep that is one nice tracking one axis system but man it sure is a lot of work. The only thing I could recommend would be to increase the delay time between the next movement and investigate how to use the Serial Monitor to show you the actual sensor values being produced, something I myself need to learn. Once i know what those numbers are the rest is a piece of cake to know for sure if the main sketch is working or not. 0000022184 00000 n
This system has been working extremely well for over 4 years now. The timer is set to stay on for 5 minutes. Each one is 200 AH. From 7.4V DC to 48V DC, we have a wide range to fit your needs. This sector is poised for immense, continuous growth: further increase efficiency with actuators from the Experts in Linear Motion. Ive had a look at the link and it looks like the store has changed the product (unfortunately this seems to be becoming more and more common with electronics on Amazon). Now this applies more to the worst case because i build everything from actuators to the electronic drivers. Notify me of follow-up comments by email.

I do not do toy tracker. You will need to follow this guide in conjunction with the original guide in order to produce the linear actuator solar tracker. That is the part i do not understand of the code. I am an expert on lithium and lead acid batteries repair and construction. Our extensive range offers both single and dual axis options. I currently have the delay within the loop set at 10000, that keeps the actuator running for ten seconds, and 5000 at the end of the loop, that causes a five second delay before the actuator runs again to drive the panels in the desired direction. I want it to rotate slowly to follow the sun but it rotates pretty fast and Im not sure if its reading my LDRs correctly. Solution is to use big car battery for now until i have all working then i deal with it, 2/ I finally got it to track after changing some codes (change the reverse to high, light to 450), 3/ It would not rotate back to East when night falls, 4/ Build the sensor correctly and make it adjustable, 5/ This thing is not stable and works erratically (that is sometimes it works sometimes it doesnt, drive me nut!). Insolis 2 actuators are dedicated for photovoltaic systems up to a static load peak of 15,000 N. Download technical information and brochures in our Download Center. It doesnt sound like its doing either from what youve said. I mentioned the duty cycle because that was a warning that came with the actuator I purchased. It sounds like youve built quite a nice sized system! Oscillating could be caused by an insufficient amount of delay at the end of the loop. startxref
I made while command which calculates the LDR sensors difference and continues after calculation reaches limit which is added there. I have a problem though, it seems to mainly want to go in one direction, when the LDRs are tested they read comparable voltages, so Im not really sure whats going on. ive been tinkering with it and making some progress but, its just getting frustrating. The parts required are as for theArduino Solar Trackerwithout the PWM servo. Why does it idle with polarity switch relay on? I accomplished this using a slightly edited code from the original and a timer. Hi Akash, I only used their code as a starting point to learn how to make something like this work. The actuator in the example doesnt provide any position feedback and we dont have any limit switches so we rely on a time based interval to determine how far the actuator has driven. Opt for maintenance-free linear motion that keeps ongoing and never compromises on performance. Night felt then the thing started to oscillate NOT reset to East. hi, Michael, I am a student and I have a project about solar tracking systems and I want to know how did you program the Arduino and why did you use the Arduino for the project, and how it works. Stay updated with our news and offers. Until you know what the LDRs are getting it is pointless and cussing as the darn thing not working the way you expect it. Will be grateful for your opinion. Im not too sure how we can PM but that would be fine with me. 0000021122 00000 n
You could do this with limit switches on each end as well. JohnV. You can use the tracking portion of the code but youll probably need to adjust the outputs to drive your motor or actuator. ZC@H3Nq4X F5
How and when do you charge this battery then? You can also send a price request directly to elero Linear actuator technology. With this methodology i was able to get everything to work along with some hardware changes. I have set this up as I had mentioned and it is working great. The measured values from the LDRs depend on the components, the wire resistance and distance from the Arduino etc, they are very sensitive. 0000017866 00000 n
In code there are condition that it wont do turning sequence if switch is activated. I doubt that the majority will do this way. 2022 Progressive Automations Inc. All rights reserved. Of course i have to add more codes for the second set of LDR and actuators. Also remember that many actuators have duty cycles and could burn up if they are operated without the proper amount of rest. With hundreds of options in stock at all times, you dont have to wait around for a perfect fit. A lot of trial and error. Hello. Using this shield should make your motor quite easy to control, you just need to make sure everything is wired correctly and then learn the programming controls. b/ move E. again for 8 seconds second time then delay multiple minutes Can someone post a screenshot of the circuit design for this project? The Arduino code has light levels and position dectection. You can increase or decrease the voltage of your actuator to suit your application. Youll then just be running two control loops, one which takes the east-west sensor values and adjusts the east-west actuator and another which takes the north-south sensor values and adjusts the north-south actuator. Your relay should have 8 pins two for the coil, two common, two normally open and two normally closed, these are all used and indicated on the diagram. The connectors that come with each actuator are changeable based on your requirements. Thing I cant get my head around does the array need to rotate or just tilt as a lot of folks seem to do? The double relay you linked above has 6 output pins and on the other side there is two choices you of input set you can place either 4 pins input (Vcc, grnd, in1, in2) or 2 pin input (VCC and RY-VCC). The reset to East is not time based, it is based on a light level threshold from the sensor. Use our product configurator to find the right solution in just a few quick steps. I build the linear actuator and using your Arduino code to track so this project is truly diy. However I figured out that there should be code also to stop turning if switch are activated while turning. 0000001331 00000 n

That will suck the juice out of the battery in a day. I had it tracked to an acceptable level yesterday. What i did was rewrite the sketch, build and use all solid state power mosfet H bridge along with opti coupler interfaces to Arduino. Insolis actuators have been specially developed for solar photovoltaic systems. I dont know about you but whenever i build something it never works the first time, NEVER! Good luck with your project, it sounds great! Now i can enjoy the fruit of my labor as they worked beautifully now.
As I mentioned, I rely on the actuator built in limit switches to shut down the motor once the actuator has moved to its extreme position. 0000021899 00000 n Do you have a photo of the connected relays because Im a beginner in arduino. Have you sketch for dual axis actuator, I have bought the relays you linked. The array will lay back down as the sun crosses over to the west. I spent lot of times scratching my head to figure that part and still not working quite right with tracking, reset to E at night and polarity switch relay turn on in idle! This way it doesnt really matter if the actuator moves another 1mm or so after the limit switch is triggered. if you are still having problems with the controller resetting to the east at night, I might suggest you investigate using the Serial Monitor to identify the sensors actual output values which should enable you to correctly set the east reset value. My question is the double relay output terminals are COM and NO or COM and NC ? The module originally linked to was a relay similar to this on a single board. %PDF-1.4 % 0000023444 00000 n My methodology is divide and conquer in fixing the sketch. Even being energized for 10 hours would only draw 1.5Ah from the battery, which from a 100 200Ah battery is fairly insignificant although wasteful. Hi Tom Ho, Glad to hear you have your system working. 0000001831 00000 n In my instance, the power supply involved, a 24vdc unit, is controlled by a timer. Hi JohnV, I had the same problem, was driving me nuts, see my comments above.
I got rid off the position counter, install end limit switches, eliminate all relays, drastically redo the sketch. Exact stroke lengths can be customized down to the millimeter or inch, with maximum strokes of over 1500 millimeter or 60 inches. That would be one solution for this thing.
You could do this by including an interrupt using the limit switch contacts, but a far easier way would be to simply reduce the time of each movement to a much lower value so that each time step is only a small movement of the actuator. Almost any microcontroller project you can think of has been tried by someone on an Arduino, so there is a wealth of information available for you to get started. Is there anything else i can do? Yep from bad power tool lithium packs. Just wondered if you have any views or could point me in a direction for more info? 
Does this make sense? Ensure you get your ideal solution for parabolic mirror placement for maximum heat effect and feedback to enable backtracking and live position sensing. The other times it comes on, around 9 AM, 11 AM, 1 PM and 3 PM allows the panels to reset to the sun position until they are completely in the down position again. So there would be no harm with removing any reference to TrackerPos? Oh i will eventually convert to power MOSFET driver and get rid off the relays too. The power supply will direct 24vdc to the actuator and 12vdc to the actuator relays and the Arduino unit. There is also one condition which follows that limit switch in while command. Our solar tracking actuators have extreme force capacity with unparalleled ruggedness to give you the ultimate reliability that you need. I made this project and managed tomake it work. For every damage it was a cussing time to buy another one and waited for it to arrive to try again. I have made the circuit and all is in place. I hope you are not using the position counter on original sketch. My aim is to make a sun lounger that can track the sun, your design seems very promising and is what I would like to use. But I didnt do it that way. This position tracking by counting from 0 to 180 is not clear at all. Thanks for the reply that site looks good, In the same light, one LDR reads 1174 Ohms and the other 1093, doesnt this mean I change my error to 81 and it should be focus? I read this diy article; however, I am having issues incorporating the code for a dual axis solar tracker using two linear actuators, East-West and North-South. All is good now, hlo sir It should be fairly straight forward to duplicate parts of the code to create a dual axis version. The breadboard diagram for this circuit is shown below: The design and code are both slightly more complex with a linear actuator as the Arduino needs to control the actuators movement duration and the direction. So youre using both the COMs as well as both NCs and NOs. Save my name, email, and website in this browser for the next time I comment. In my code I deleted all mention of it and depend entirely on the limit switches. Now I need your help on this only thing left. I only had to change the values for calibration to -10 and the value for (eastLDR<450 && westLDR<450) to get it to work properly. Can you explain how the time base tracking for the East reset at night work? Top of the day to you sir.
Does the panel only move a small amount or is it erratically moving? That thing sucked never worked for me until i get rid off the codes. 0000021286 00000 n Many if not most people just buy ready to use, slap and adapt to make it work. 44 0 obj <> endobj Upgrade your unit today with IP69K ingress protection for peace of mind and long unit life. I had built 8 already. I assume that you are referring to the trackerPos variable? Im unable to see it for some reason. Hi Tomi, I would love to have a dual axis sketch. This combination signicantly increases the efciency of complex solar tracking systems and ensures a quicker amortisation of investment costs. I use a small solar panel to keep it charge up. I appreciate your help! Hi Michael, This thing is driving me nut but i am not giving up. The correct relay to use is something like this https://amzn.to/3ewHBHw A 5V DC double pole relay is used to reverse the polarity of the supply to the linear actuator. Reset to E. for next day. I dont have pictures of the setup as the moment but Im not sure that they will help as there is a very wide range of different relays available and they have very different connection setups. Alternatively, for a cost-effective approach, useone actuator with added gear motor. That was my biggest headache and time waster. Have you used the exact circuit and code as in this example or modified it? Hi John, Hi Tom Ho, My system is different from that published in DIY. The difference between the two with equal light on both LDRs is what you should change your error to. I havent got to implementing it yet, but I have discovered a problem with the original circuit that I missed previously. Build or slap together purchase is easy. I still dont have it working consistently for tracking and reset to East is not working at all. Hi Tommy,
P.s: For anyone attempting to do the solar tracker, i cant emphasize enough the importance of using sketch of LDR reading. These solar actuators are available for both portable and utility-scale trackers and are compatible withindustry leadingcontrol systems. I would suggest running the system with the Serial monitor open on your PC and sending the measurements from the LDRs to the monitor. I just wondered if you had any thoughts. I am thinking of remove that code and just use the limit switch. I want to try it too if there is one. Main reasons are : a/ the photoresistor value in the code Im doing a similar project and Im having trouble controlling the motor with the relays. After many trials and errors and tribulations I am closed to what i want it to do. Our precision solar linear actuators offer accurate positioning to get optimal exposure of the sun. Include is the sketch and i cant get it to do what i want it to do. 0000018522 00000 n
You are correct in that it should move away from an ldr if you cover it with your finger. I try to rebuild the solar tracker. This doesnt seem to work, only a couple of times has it actually reversed, Im thinking its probably to do with the LDR spacing and separated shielding from the sun. /* xxxxxxx*/ is your best friend. Isnt the Tracker Position redundant in this sketch since there is no Tracker Position pin or any other reference to identify the tracker position? Analog or digital, we offer a variety of feedback options such as hall effect sensors, potentiometers, reed switches and limit switch feedback.
