This app creates a simple musical instrument using Scratch and a PicoBoard. When the app is running, the program implements a forever if-else loop that tests to see if the button is pressed on the PicoBoard. When the PicoBoard button is pressed, the program takes the y position of the sprite and sets the MIDI instrument, takes the x position of the sprite to set the overall volume of the music, then reads the sensor value and maps the sensor reading to musical pitches as long as the button is pressed. The sensor value is processed and offset to return notes within an octave.
