“An electronic sun-dancing sun tracker.
A maker is always sensitive to new and funny things. One day, I watched a video in which a sunflower moves along with the sun. I had a sudden insight then. Why can’t I make an electronic device imitating this biomechanism.
In the following days, I began to carry out my solar tracker project. I selected the crowtail as the microcontroller board, and picked up the components and accessories in our warehouse. Then I assembled these parts together. At last, I tested it using the LED on my phone. You know what, it worked perfectly.
I was so excited and posted the demo video on the social media. I was surprised that many people liked and shared this video, and some of them even sent me messages saying that they want to make this project, too.
So I redid this project and made a specific tutorial to help more people make it. Here we go.”
