Circuit Documentation

Summary

This circuit utilizes an ESP8266 NodeMCU microcontroller to interface with two LEDs (one red and one green) and a sound sensor. The red LED is activated based on a specific condition, while the green LED is controlled separately. The sound sensor detects sound levels and outputs a signal to the microcontroller, which can be used for further processing or triggering actions.

Component List

ESP8266 NodeMCU

• Description: A low-cost Wi-Fi microcontroller with GPIO pins for interfacing with various components.
• Purpose: Acts as the central control unit for the circuit, processing inputs from the sound sensor and controlling the LEDs.

LED: Two Pin (Green)

• Description: A standard two-pin green LED.
• Purpose: Provides visual feedback or indication based on the circuit's logic.

LED: Two Pin (Red)

• Description: A standard two-pin red LED.
• Purpose: Provides visual feedback or indication based on specific conditions in the circuit.

Sound Sensor

• Description: A sensor that detects sound levels and outputs a corresponding signal.
• Purpose: Monitors sound levels and sends an output signal to the microcontroller for processing.
