(1) Play a sound from a musical instrument such
as a keyboard. (Single note is desirable)
(2) Analyze the pitch of the sound with Arduino.
(3) Each animal corresponding to the note of C,
D, E (Do, Re, Mi) advances.
For example, when the sound of E(Mi) is played,
the third animal (because E(Mi) is the third
note of C,D,E...) moves forward.
If the note F is played, the fourth animal moves
forward.
(4) The animal in the foreground wins when one
song has finished playing.
Older versions used fans to advance balloon
animals. |
