Story

This project demonstrates the use of two LEDs along with two Push Buttons.

Objective

For one set of LED and the Push button, when button is pressed LED is set ON and when the button is released, LED will be set OFF. for the other set, its the opposite effect.

Code

Two LEDs and Two Push Buttons with opposite effect

const int BUTTON1 = 2;
const int BUTTON2 = 4;
const int LED1 = 8;
const int LED2 = 12;
int BUTTONstate1 = 0;
int BUTTONstate2 = 0;

void setup()
{
  pinMode(BUTTON1, INPUT);
  pinMode(BUTTON2, INPUT);
  pinMode(LED1, OUTPUT);
  pinMode(LED2, OUTPUT);
}

void loop()
{
  BUTTONstate1 = digitalRead(BUTTON1);
  if (BUTTONstate1 == HIGH)
  {
    digitalWrite(LED1, HIGH);
  } 
  else{
    digitalWrite(LED1, LOW);
  }
  BUTTONstate2 = digitalRead(BUTTON2);
  if (BUTTONstate2 == HIGH)
  {
    digitalWrite(LED2, LOW);
  } 
  else{
    digitalWrite(LED2, HIGH);
  }
