Check out this neat 8-bit Annoying Person Remover project. It uses an old NES as the shell or enclosure of the project, and a whole bunch of Adafruit components. It basically senses when a person has entered your office, plays some cool Nintendo music, and starts a countdown timer. That person has just a few minutes to say what they need to say before the timer goes off.
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.
