......dang, sitting here by myself and no one to ask.....
if I have pin 12 on my Mega putting out a 50% duty cycle square wave at normal PWM frequency.....and I want to convert it to the average voltage DC. What is that called?
So 0-5 vdc square wave ~490 hz coming out of the Mega I want to turn that into 2.5v DC.
What's that called?
