Audio: Sound Level Meter - Intensity

4 years 11 months ago #1876 by Ray
The code structure is very similar to www.electrosmash.com/forum/arduino-audio-meter/

It reads the analog input signal (A0) and depending on its level it lights up the whole panel, so if you play louder or harder the panel goes brighter.
  • You can adjust the amount of signal going into the effect with the gain potentiometer
  • I have included all the libraries in the same folder so you don't need to install them. Just unzip and compile!

This is the complete code:
