So it seems it is not the servo but the analog in on the Pico that is causing the problem. I read somewhere that the analog pins were subject to noise due to internal paths inside the chip. Thanks for the experimentation.
The older R3 Arduinos seem to be worse than either the Pico or newer R4 Arduinos with respect to Servo jitter. Do you know a clean way to mitigate this?
@@arnoldschmucker9977 I don't recall having that problem with the R3. I think I remember the analogRead being rock steady at the 10 bit (0 - 1023) resolution of the R3. That said I am getting a little forgetful the older I get.
@@keithlohmeyer- I agree, the analog read statement is rock solid. There does seem to be a problem in the PWM signal on the Servo side. I am working with too little data to make a definite conclusion. Too bad I don’t have time or money to make a formal study.
