- Well , I thought I could create a Real time visualization of sound through a microphone. It kinda worked. I built the circuit using a LM 386 amplifier and a electret microphone and a few led in the order from yellow to green to red.
- Due to high sound picked up by the microphone. it kept being lit all the time with minor jumps. Anyway, the help i got was from the site given below.
- Here are some pics.
