Circuit Documentation

Summary

This circuit is designed to control multiple AC LED bulbs using an ESP32 microcontroller and a 4-channel 5V relay module. The ESP32 is responsible for triggering the relays, which in turn switch the LED bulbs on and off. A current sensor is included to monitor the current flow, and a voltage sensor could be added for voltage monitoring (though it is not wired in this design). The circuit is powered through a socket that provides the AC power to the bulbs and the current sensor.

Component List

ESP32 (30 pin)

• Description: A microcontroller with WiFi and Bluetooth capabilities.

Relay 4 Channel 5v

• Description: A relay module with four channels that can be individually controlled.
• Purpose: Switches the LED bulbs on and off based on signals from the ESP32.

LED bulb AC / Bombillo AC

• Description: Standard AC-powered LED bulbs.
• Purpose: Provide lighting when powered.

Current Sensor

• Description: A sensor that measures the flow of electric current.
• Purpose: Monitors the current consumed by the circuit.

Socket

• Description: An AC power socket.
• Purpose: Provides AC power to the circuit.

Comments

• Description: Text placeholders for additional information or notes.
• Purpose: Used to include comments or annotations within the circuit design.

Note: The provided code is a template and does not include specific functionality. It should be expanded to initialize the GPIO pins connected to the relay module and to handle the control logic for turning the LED bulbs on and off based on some criteria (e.g., sensor input, time of day, external commands via WiFi, etc.).
