L 4.1 | LED & Push Button

Project Name: Combination of LED and Push Button

Aim of the project:  The Arduino board has one built-in on digital pins and analog input using Push Button

Component:

1. Arduino
2. Breadboard
3. Led
4. Jumper Wires
5. Push Button

Circuit Diagram:

Code:

int ledPin = 13; // choose the pin for the LED
int inPin = 7;   // choose the input pin (for a pushbutton)
int val = 0;     // variable for reading the pin status

void setup() {
  pinMode(ledPin, OUTPUT);  // declare LED as output
  pinMode(inPin, INPUT);    // declare pushbutton as input
}

void loop(){
  val = digitalRead(inPin);  // read input value
  if (val == HIGH) {         // check if the input is HIGH (button released)
    digitalWrite(ledPin, LOW);  // turn LED OFF
  } else {
    digitalWrite(ledPin, HIGH);  // turn LED ON
  }
}

Runs Steps:

These are the steps you need to follow in order to be up and running:

1. Get an Arduino board
2. Download the Arduino environment
3. Install the USB drivers
