The smartphone app SMTH (“Send Me To Heaven”) uses a smart phone’s accelerometer to measure the height the phone reaches after you toss it in the air. (The marketing tagline for the app is, “Probably the last game I´ll ever play on my current phone.”) Roger Meike, one of the creators of SunSPOT, a very early Internet of Things device, put together a nice tutorial on just what an accelerometer really measures and the calculations the app performs.
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.
