"acqNote" gets the acceleration in the 3 directions from the sensor, selects the highest and returns the associated frequency. tone (board.D5, 440, duration 1.0 ) You should hear a 440 hz tone, or an A4 note, played for one second.

Try the following to play a 440 hz tone for 1 second: Download File. Int sensorValue3 // value read from the Accelerometer's second pin Now you'e ready to use the tone function in SimpleIO to play a tone on a pin connected to a piezo buzzer.

The music is "where is my mind" from The Pixies, which is really easy to play. Currently I am collecting funds against Cancer, please donate!Īttempt to play a cool music with a crap speaker, hoping that the "cool" will compensate the "crap".
#Arduino piezo tricks code
The code is basic : the song rhythm is implemented and before each time step, the glove senses the gravity direction and chooses one of the three notes of the song.
1 song able to challenge the crap sound of the speaker If you however downloaded the official version and this trick did give you.
The aim of this project is to generate music through motion thanks to accelerometers. Getting started with Arduino and a WS2811 or WS2812 LED strand using NEOPixel.
