Light source/solar tracking module

1. The power supply uses a 5-5.5V DC power supply with a current of less than 1.5A.

2. The motor uses a geared motor, the slower the better. If the motor speed is too fast, it may cause the motor to align with the center of the light source, but swings left and right, but does not shake. This circuit uses a short delay of anti-shake.

3. When the motor and the board are connected, the positive and negative poles are not divided. If the motor is found to rotate in the opposite direction to the light source during the test, the motor line can be changed.

4. The power supply must be regulated to 5.5-5.5V and cannot be directly connected to the solar panel.
