Emily VelascoDoes anyone on here know if the capacitor-resistor combo attached to a pwm output pin of an Arduino gives a decent analog output?
Chip@MLE_online For some value of decent, sure. This is a very common way of doing a crude DAC. As long as the other side isn’t sensitive to the switching noise, and you don’t need to switch it any faster than the filter will let you, you’ll be fine.
