I wanted to make something useful that used LEDs without having to program an Arduino or anything like that. The idea I came up with was to add LEDs to artificial flowers and make it decorative by putting them in a clear vase filled with clear/opaque glass marbles. The addition of more LEDs inside the vase would make it even better.
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.
