Circuit Documentation

Summary

This circuit consists of an Arduino UNO microcontroller, a sound sensor, a red LED, and a resistor. The sound sensor detects sound levels and sends a signal to the Arduino. Based on the sound sensor's output, the Arduino controls the LED, turning it on or off.

Code Documentation

Arduino UNO Code

int soundsensor = 13;
int led = 3;

void setup() {
    pinMode(soundsensor, INPUT);
    pinMode(led, OUTPUT);
}

void loop() {
    int statusSensor = digitalRead(soundsensor);
    if (statusSensor == LOW) {
        digitalWrite(led, HIGH);
    } else {
        digitalWrite(led, LOW);
    }
}

• soundsensor: Pin D13 is used to read the output from the sound sensor.
• led: Pin D3 is used to control the LED.

setup()

• pinMode(soundsensor, INPUT): Configures the sound sensor pin as an input.
• pinMode(led, OUTPUT): Configures the LED pin as an output.

loop()

• statusSensor = digitalRead(soundsensor): Reads the status of the sound sensor.
• if (statusSensor == LOW): If the sound sensor detects a low signal, the LED is turned on.
• else: If the sound sensor does not detect a low signal, the LED is turned off.
