The note frequencies in the code correspond to the Hot Cross Buns song and need to be adjusted for other songs.
# These are the frequencies of the three notes. note1 = 261.63 note2 = 293.66 note3 = 329.63
By default, the tilt value to switch from one note to another is 7° and needs to be adjusted depending on the balance board.
# If the balance board tilts beyond "tilt" degrees, different notes will be played. tilt = 7
By default, the time to keep the board roughly horizontal is 0.7s. This allows quick modification of the tilt position and playing note 1 followed by note 3 (or vice versa) without playing note 2.
# Time (in seconds) to keep a horizontal position before note2 is played. # This allows to switch from note1 to note3 (or vice versa) without playing note2. horizontal = 0.7
