This guide is for people that wish they had a soundtrack to their life. Using a PIR sensor and magnetic door switch with a Raspberry Pi, you’ll be able to play a sound file every time you open a door. More specifically, it will play a pre-recorded sound file based on whether you are entering (applause!) or leaving (booooo!).
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.
