Circuit Documentation

Summary

This circuit involves an Arduino UNO and an Arduino Nano, which control a series of LEDs, a 16x2 I2C LCD, an IR receiver, an SD module, and a 5V 8-channel relay module. The circuit also includes several resistors, solenoids, and a power supply module. The Arduino UNO is primarily responsible for handling the IR receiver and the SD module, while the Arduino Nano controls the LEDs and the 16x2 I2C LCD. The relay module is used to control the solenoids.
