1. The guitar signal is AC at around 1.5 volts max, and it will be running into the LM386.
2. The output of the LM386 should be amplified up to a max of 5v and it will still be A/C (I assume) so I need to use a rectifying diode setup to convert it to DC.
Also, I've heard there is an electrical engineering software program out there that will simulate electronics so you can build your circuit on the computer without having to buy parts and try them out. This would be immensely helpful. Anybody know what the program is called so maybe I could help myself?
I'm essentially creating an LED light that pulses based on the guitar input's strum patterns.
Is there some reason that you've decided to use the lm386?
