ESP32-CONTROLLING LED USING SWITCH

ESP32-CONTROLLING LED USING SWITCH

Aim:

Controlling LED using a Switch

Objective:

Understanding the working of switch. Turn ON the led when switch is pressed and Turn off when it is released

Connections:

Pin Mapping:

Switch	I012
LED	I04

Program:

void setup() {

pinMode(4, OUTPUT);//Initialize the output pin 

pinMode(12, INPUT);//Switch is connected to pin 12

Serial.begin(9600);

}

// the loop function runs over and over again forever

void loop() { 

if (digitalRead(12)==HIGH)

{

digitalWrite(4, HIGH);// Turn the LED on

delay(1000);   // Wait for a second.

digitalWrite(4, LOW);  // Turn OFF LED

delay(1000); // Wait for a second.

}

}
