Units – Makey Unit MEGA328P – 16Keys Fruit Piano



Description


MAKEY Unit is inspired by an Invention kit called Makey Makey which brings the concept that users can connect everyday objects to computer programs. Using a circuit board, alligator clips, and a USB cable, the circult uses closed loop electrical signals to send the microprocessor either a keyboard stroke or mouse click signal. We’ve tried connect a bunch of fruits, one for each key,to this Unit. When you touch the apple, you make a connection, and Makey sends the processor a keyboard message. The buzzer inside or speaker on M5core will exhibit the key value, so instead of using a keyboard, you can make a fruit piano.

This Unit communicates with the M5Core via the GROVE A I2C(0x51).
