 "LumiTrack" is a small instrument capable of tracking a light source in real time. Its core components include two photoresistors, a comparator circuit, and a DC geared motor. First, light shines on the two photoresistors and is converted into different electrical signals. Then, the comparator circuit processes these two signals to determine the direction of the light source. Based on the comparison result, the control circuit drives the DC motor to align the solar panel with the light source. Finally, the electrical energy generated by the solar panel is stored in a lithium-ion battery via a CN3065 chip.
