VU Meter using PIC Microcontroller.
No audio cable needed. Just plug in the power cord.
It can be placed anywhere. Very high sensitive microphone can receive even whisper.
(IC LM386 which are used in spy microphone circuit.)
PIC 16F628A microcontroller is used to do DSP (Digital Signal Processing) and AGC (Auto volume gain controller).
Currently it has 12 modes of running light.
If there is no sound for a while, it will switch to running light mode.
Then switch back to VU meter when sound was detected again.
