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 reads the slider sensor value and maps the sensor reading to musical pitches from the selected pitch set list as long as the button is pressed. The sensor value is processed and offset to return notes across the MIDI range.
