Basically it’s a skull that looks at you, says hi, and then beckons you to ring the doorbell. Yes, I’m cheating and using a single “eye” and an eye patch…maybe next year I’ll push it a little further.
PIR sensor notices motion, activates the “eye” (pingpong ball with an adafruit webcam sticker for a pupil), then triggers the audio FX board to play a sound out the speaker, then the neopixel ring activates around my doorbell.
Control is from an Arduino Micro feed with 5v USB, only downside here is that I can’t push the power usage too much further.
In the dark this looks really freaky, especially when I have the eye rotate into position from the back of the skull.
It’s my first project using the Audio FX board, and I got to say it’s awesome! All audio recorded and edited with Audacity in Linux, then exported to OGG format.
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.
