audio How to make LED bar graphs to measure intensity


Posted on Feb 5, 2014

Make those LEDs into LED bar graphs that will show the intensity. For example, I want a song with a loud base to make the bar graph shoot up to the top. The bars of the LED bar graph I would like to just be individual LEDs. I was getting the effect with an arduino but I was hoping there was easier way to do this.
