Using Raspberry Pi with PIR motion sensor #piday #raspberrypi @Raspberry_Pi

I have been using the Arduino for a few years now and recently curiosity got the better of me with the excitement around the Raspberry Pi. I purchased my first Raspberry Pi and since my interest is more in line with interacting with the physical than just having a small computer, I needed a second project. Of course, the first project was to blink an LED!

For my second project, I decided to expand on the first. I still use output to blink an LED, but now I also use input to decide when to blink the LED. The way this project works is by sensing motion using a PIR, Passive Infra-Red, sensor.

Using the Adafruit Raspberry Pi Cobbler, here’s how I connected the Raspberry Pi GPIO pins to the breadboard and wired up the PIR sensor and LED.
