I don't understand why the filter didn't work, and I don't understand why the meter reads higher with no NPN transistor than it does with the transistor.
I thought that a PWM pin would sink the same amount of current as it would source, but apparently that is not the case.
I know that's what it says in the datasheet
I get two different meter readings, and it's only correct when I hook it up to GND.
