This project was originally made as a Physics assignment. The assignment was to create something with an Arduino, this includes designing, programming and building.
We chose to make a moving solar panel. The panels automatically move towards the place with the most light. This ensures optimal power generation.
In order to come to a proper design we looked at several existing designs. From there we started to come up with different design options.

Step 1: Requirements
- 4x 5.5V 90mA 0.6W Mini Solar Cell 6.5 x 6.5
- 1x Arduino Uno rev3
- 2x SG90 Mini servo (180°)
- Jumper cables
- Soldering Iron
- Soldering tin
- 3.3mm multiplex
- Hot glue
Step 2: Building
In order to make sure that each of the 4 solar panels know how much power they are generating. We are going to need to use 4 of the analog ports. The ports can exactly check how much power they are generating.
The 4 solar panels are placed at an angle so there's a bigger difference between the amount of power they are generating. 2 servos are used to allow the panels to move in each direction.
The schematic can be found in the picture above.
