I am no piano expert nor do I have knowledge about notes, all I understand is that high frequency makes twitty sounds and low ones make beatty sounds.
Think about a piano that has no keys, makes some tone from movement of hand. That’s what this project is all about.
The micro:bit has an accelerometer and a magnetometer. By moving the board 360 degree round and upward/downward can be sensed with these sensors. There are block functions to generate square waves and showing text on 5X5 matrix. By adding an external speaker/buzzer/peizo tone can be created. Combining all these an air piano can be realized.
Each Monday is Micro:bitMonday here at Adafruit! Designed specifically for kids and beginners, the micro:bit is a pocket-sized computer that you can code, customize and control to bring your digital ideas, games and apps to life! Play, learn, explore: get started with micro:bit! Adafruit is an authorized Micro:bit reseller- check out all of our posts, tutorials and Micro:bit related products!

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.
