Hello! I need to get an analog output from Arduino. I read that you can do this with PWM output. My question is: I need to add a low pass filter to the PWM output?
Thank you very much!

Yes, that is correct.
Yes. An Intergrator. A RC intergrator. I did a sim, the value are : 100 K and 0.1 uF. But you will need a op-amp buffer to increase the current output. Use a sim and see what happen.
