hey all
I already start a tread for the automated motor fader i try to instal in my desk, but maybe the specific question I have right now is better posted here
System drive the motor with a PWM (PIC18F output) and H-bridge (L293D)
I want to smooth this PWM, to have more silent systeme, mechanical noise and also electronic noise leaking to my audio part of the fader
something like a variable DC relative to the PWM duty cycle
my question is simple, can I add an active LPF/integrator stage between PIC output and H-bridge?
Can I add resistive load to a PIC output?
best
