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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
