This activity demonstrates how to design and play a simple wireless musical keyboard using 3 pushbuttons, a piezospeaker and a wireless RF Transmitter and Receiver module. Two HomeWork boards will be used: one outfitted with three pushbuttons and an RF Transmitter module, and the other with a piezospeaker and an RF Receiver module. When complete, you will be able to press buttons on one board and a tone will play through the piezospeaker on the other.
