Hello, In this Instructables let's learn to control a buzzer with a PIR interfaced with Arduino.

Let's get started!

Step 1: Components Required

Components required for making this projects are:

  • Breadboard
  • Arduino Uno
  • PIR sensor
  • Jumper wire
  • Buzzer

Step 2: Adding PIR Sensor

PIR connection is as follows:

  • The VCC pin of the sensor is connected to the positive railing of the breadboard
  • The GND pin is connected to the negative railing of the breadboard
  • The signal pin is connected to the digital pin of the Arduino board.

Step 3: Buzzer Connection

  • Solder the pins of buzzer to male to male jumper wire
  • connect one of the pins to pin 2 of the arduino board and other to ground connection of breadboard.

Step 4: CODE

Step 5: OUTPUT
