Magic Wah: Wireless Musical Expression Pedal
The Magic Wah wireless pedal is a musician’s dream accessory.
The impressive system—which consists of two devices that communicate
with each other point-to-point using the 802.15.4 PHY layer—includes
a pair of MC13192 SARD boards containing an MCS908GT60 microcontroller,
an MC13192 RF transceiver, and two accelerometers. To operate
the pedal, the musician must wear a transmitter on his foot.
The receiver plugs into the musical instrument’s signal path.
The transmitter constantly monitors the angle of the musician’s
foot and transmits the data to the receiver.
