Circuit Documentation

Summary

This circuit is designed to interface an APDS-9960 RGB and Gesture Sensor and a KY-038 sensor module with an Arduino Nano microcontroller. The circuit also includes a 4-channel relay module that controls four AC bulbs, powered by a 12V power supply. The Arduino Nano is responsible for processing the sensor inputs and controlling the relay module, which in turn switches the AC bulbs on and off.
