Circuit Documentation
Summary of the Circuit
The circuit described by the provided inputs consists of an ESP32 microcontroller, a 2-Channel Relay module, two bulbs, an AC power supply, and a USB male 2-pin connection. The ESP32 is powered via the USB connection and controls the relay module, which in turn switches the two bulbs on and off. The AC supply provides power to the bulbs through the relay contacts. The ESP32's GPIO pins are used to control the relay inputs, and the ground and power lines are distributed among the components to complete the circuit.
