Push button sensor

HOW TO USE PUSH BUTTON SENSOR

INTRODUCTION:

In this blog we gonna  talk about push button sensor.

you all can seen that thereis three pin present so 1st start with "s" signal it is sensor signal and it is connect any of the pin in digital section of arduino.the middle pin is +ve pin it is connected in 5v pin of analog section and the third pin connect with ground pin.

you all can check the example code of arduino software.

Things Required:

• Arduino
• Breadboard
• Jumper wire
• LED
• resistor (220ohn)

CODE:

// constants won't change. They're used here to set pin numbers:

const int buttonPin = 2;     // the number of the pushbutton pin

const int ledPin =  13;      // the number of the LED pin

// variables will change:

int buttonState = 0;         // variable for reading the pushbutton status

void setup() {

  // initialize the LED pin as an output:

  pinMode(ledPin, OUTPUT);

  // initialize the pushbutton pin as an input:

  pinMode(buttonPin, INPUT);

}

void loop() {

  // read the state of the pushbutton value:

  buttonState = digitalRead(buttonPin);

  // check if the pushbutton is pressed. If it is, the buttonState is HIGH:

  if (buttonState == HIGH) {

    // turn LED on:

    digitalWrite(ledPin, HIGH);

  } else {

    // turn LED off:

    digitalWrite(ledPin, LOW);

  }

}
