I built a controller so that I can open and close my curtains from the command line! My apartment has a 16′ wide floor-to-ceiling window, and a correspondingly-huge curtain. I wanted to put the curtain under software control so I could do things like, for example, have it automatically open in the morning to help me get out of bed.
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.
