Circuit Documentation

Summary

This circuit involves an ESP8266 microcontroller, a 4-channel relay module, multiple flush switches, AC bulbs, and power sources. The ESP8266 controls the relay module, which in turn controls the AC bulbs. The flush switches are used to provide input to the ESP8266. The circuit is powered by both a DC power source and a 240V AC power source.
