You can create gain by inserting a resistor between the two 100k resistors and the output.
I know the circuit I found does not allow for any conditioning of the PWM. I assume I will need some sort of low pass filter on the op-amp input.
Hi, Im having troubles with 24V AC valve as well, I figured out the way to get 10V DC signal, but the problem is that when I connect the valve (-) to arduino GND (the walve is powered by 24V AC) the current of the 24V AC transformer hits the skies, any suggestions ?
Did you measure the 0-10volt signal input with a DMM.Could be that 10volt is already on the input/ground of the device when nothing is connected to it.0-10volt has been covered before.https://forum.arduino.cc/index.php?topic=340922.0Leo..
