Trigger DC Motor with PIR Sensor & Arduino – Complete Guide

Welcome to my comprehensive Arduino tutorial where I’ll show you step by step, how to use a PIR sensor to turn on a DC motor using an Arduino Uno. From wiring each component to an Arduino Uno, to writing a variety of Arduino code examples from scratch, you’ll be able to build your own motion-activated DC motor project and control it with Arduino and a PIR sensor.

Whether you’re building an automated gadget, an interactive art installation, or a Halloween motorized prop that comes alive when someone walks by, turning on a DC motor with a PIR motion sensor is a useful Arduino project for a lot of applications.
