Figure 1
Solar powered circuit that reflects the sunlight arbitrary by using a mirror attached to a small DC motor.
The circuit of the project is very simple. It uses only two transistors, a DC motor, a solarcell and a few other components.
First start building it on a protoboard and when you are sure that the circuit is working fine, you can assemble the circuit on a perfboard or a PCB.
You can change the parts or value of the capacitor to observe what changes. A protection diode can also be connected parallel to the motor to prevent the transistors against high voltage transients.
The circuit can be placed in a lid so it will be kept clean and safe.
