I used a Raspberry Pi to re-invent my old 1960’s wall box as a controller for my wireless home media system (SONOS). It looks wonderful in my kitchen with its chrome and warm lights. Everyone loves dropping in a quarter, seeing the credits light up, and hearing it clunk and whirr as it selects a song.
The RPi is housed inside the wall box and runs a program that polls the GPIO for pulses from the wallbox. It decodes the pulses into a song selection and using UPnP protocols over my home wi-fi, adds the song to the SONOS queue.
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.
