Making Music with a Microcontroller
Using a piezoelectric buzzer element, we can turn voltage into pressure waves, or sound. This project demonstrates code which can play any desired tone, and plays a song while showing each syllable on the LCD screen.
You can download the source code. (Start with one of the projects included with the kit, and modify the Makefile to reference this file.)
