Arduino Program for Turn On Led through Push Button

Component Required

• Arduino Uno
• Breadboard
• Pushbutton
• Led
• jumper wires

Arduino Code

int led = 4;

int switch = 2;

void setup() 

{

  pinMode(led,OUTPUT);

  pinMode(switchh,INPUT);

}

void loop() 

{

  if (digitalRead(switchh) == 0)

    digitalWrite(led,HIGH);

  else

    digitalWrite(led,LOW);

}

Note: This Arduino Code is also can be used for controlling any electrical or electronics components like Relay, Buzzer, Bulb, Fan, etc.
