audio fx sound board ACT pin

by zenSutherland on Wed Jun 12, 2019 9:53 pm

I have a dumb question. The ACT pin on the Audio FX Sound Board will go LOW during 'play' activity, so if I put an LED from it to +v I assume it will light up, but will it draw any current when it's not in use because there would be some voltage on both sides of the LED. I'm concerned about power usage because I'm powering the whole thing via AA Batteries, and I don't want to draw power while it's not making sound.

Thanks, I'll turn down my radio and listen for your answer. :)
