Hello all,
I´ve been reading quite a lot about different circuits on how to make a mic signal or jack signal turn into blinking leds.
I like to understand what I'm doing when following the schematics from other people, so I can in the end, build on my own.
I tried different things, when I came up with the following solution attached below.
I imagined I could use my TIP31 transistor to amplify a first time the signal and take this to the LM386, giving another 20x and send it to the LEDs.
Could someone help me debugging it? When I turn on the power, the Leds are constantly bright and the mic signal has no effect into it.
Thanks!
