The initial setup for the Doorbell was dead simple. A push-to-make button connected to a GPIO on the C.H.I.P which caused some code to randomly play out various MP3 files over the audio-out to some big speakers cunningly hidden near the door.
This year I thought “I’ll add a simple LCD message to guide people”. Then I thought I’d use my Adafruit OLED screen. Luckily most of the code I needed was out there and it was case of a few evenings of tying it all together.
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.
