This tutorial we will demonstrate how to detect motion from PIR Sensor using Arduino, ones the PIR detect a motion it will trigger the LED as the output.
Electric Parts Require
- 1x Arduino
- 1x PIR Motion Sensor
- 1x LED
- 1x Jumper Cable
Please follow this schematics below to setup this lab testing.
