IC LM386 + microphone

This time i assembled a circuit with a LM386 IC, it is a low power amplifier. I connect a mircophone to this amplifier, in the second photo you can see how the crocodiles have to be attached to the 3.5mm plug (white GND, Yellow (+) ) in this case i used a headset microphone, but it can be replaced by an electret microphone. On the LM 386 output i connected a LED, which lights brighter when the sound (music) is louder.
