Introduction: DIY Miniature Solar Tracker

About: Awesome Electronics Tutorials, Projects and How To´s

In this project I will show you how to create a solar tracker which like the name implies can follow the movement of the sun throughout the day. And at the end I will show you the energy harvest difference between a solar tracker mounted solar panel and a flat mounted solar panel. Let's get started!

Step 1: Watch the Video!

The video gives you all mandatory information about the solar tracker. During the next steps though I will give you some additional information.

Step 2: Order Your Components!

Step 3: 3D Print the Solar Tracker Parts!

Here you can find the utilized model on thingiverse: https://www.thingiverse.com/thing:708819

And here you can also download the remaining part that I created by myself.

Step 4: Create the Circuit and Upload the Code!

Here you can find the schematic and code for the project. Feel free to use it to create your own solar tracker.

Step 5: Success!

You did it! You just created your own Solar Tracker!

Hi.
Congratulations, great design.
I made it and it works great.
I have a question about controlling relays instead of stepper motors.
Could you tell me how to do it.
I have a turntable from a CCTV camera powered by two AC motors, I want to control them instead of stepper motors. I want to use it to move the solar panel.
My e-mail: damian-sroka@wp.pl
Thank you for your help.

Olá, tudo bem, eu fiz esse ótimo projeto, mas não funcionou como o
vídeo.
Funciona o oposto da luz, fugindo, está na posição abaixada. E
isso treme muito.
Para iniciantes, fiz essas compras.

Já os resistores de 1K já tentaram colocar o mesmo,
sendo 975 R
Como mostro um vídeo? E fotos também?
Eu queria colocar as fotos lá também em Eu fiz.
Obrigado pela sua atenção.
