Equalizer Display with LED
The goal of this tutorial is to create a device that takes a standard headphone audio signal (from a laptop), interprets it and outputs the voltage amplitude onto an LED bar. The LED Bar should change rapidly with the flow of the music beat & rhythm.
The PIC will use its internal analog to digital converters to accomplish the above task. The completed circuit will be all done on a small breadboard. I must add the circuit and the song in the video go well together.
