PIR Controlled Buzzer Using Arduino

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
