Use case: since the kitchen door in my 2 apartment silences all sounds from outside the room, I was never able to hear my doorbell when the music was playing in my kitchen.
As me and my friends do like to party while blasting music from our speakers in my kitchen, we were never able to hear the doorbell once the door was closed. People had to ring my phone in order to get in.
Luckily, one guy at the partycame up with the excellent idea to “hook up some kind of microphone and ring a sound if the doorell rings“.
The idea seemed nice, so we brainstormed the possiblities over a couple of beers with my tech-savy friends.
It hat to be a bit more flashy than just a doorbell sound, so instead of using my speakers we decided to use my Philips Hue lights instead to create a cool light effect to announce new guests!
All of the lights were set up in the kitchen already, so we went for a blink the lights if the doorbell rings approach.

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.
