Bachelor Assignment

The assignment was to build a solar tracker as efficiently as possible. We decided to build one that is controlled by a microcontroller-circuit. A Real Time Clock was used to calculate the position of the sun with a time-based algorithm. This is the circuit we designed:

Here are some pictures of the fully soldered circuit:



I also built a prototype in wood to see if it works well. The solar tracker only moves a few times a day. Here is a video taken when it did:
