Light Board is a Google-made game demo for both iOS and Android that works across phones […] I set up a little home base full of colored target markers [on my iPhone], and someone from Google did the same on an Android phone across the room. I shot virtual missiles at their target, and they shot at mine. Whoever lights up all the targets first wins.
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.
