Tracking the rotation of our Earth
Here i show a simple system i built to track the Sun passing the sky. Some people call it Sun tracking, but i dont like it because it suggest that the Sun is moving. Yeah the sun is indeed moving, but it is not what is tracked.
Electrical parts used:
1 x Photoresitor, 1 x Transistor, 1 x Solarpanel, 1 x Operational amplifier, 2x Potentiometers, 1 x Motor with gear
Operation:
If the Photoresistor is under direkt Sunlight the Motor is switched on. This rotates the complete device. This will move the shadow over the Photoresistor. This switches of the Motor.
