Luminoscity 0:c02f01feda7b 5 Buzzer
Luminoscity 0:c02f01feda7b 6 The example use a buzzer to play melodies. It sends a square wave of the
Luminoscity 0:c02f01feda7b 7 appropriate frequency to the buzzer, generating the corresponding tone.
Luminoscity 0:c02f01feda7b 8
Luminoscity 0:c02f01feda7b 9 The circuit:
Luminoscity 0:c02f01feda7b 10 * Buzzer attached to pin39 (J14 plug on Grove Base BoosterPack)
Luminoscity 0:c02f01feda7b 11 * one side pin (either one) to ground
Luminoscity 0:c02f01feda7b 12 * the other side pin to VCC
Luminoscity 0:c02f01feda7b 13 * LED anode (long leg) attached to RED_LED
Luminoscity 0:c02f01feda7b 14 * LED cathode (short leg) attached to ground
Luminoscity 0:c02f01feda7b 15
