I recently got into Auduino and got my self the starter kit.
I am really enjoying it so far.
There is a question I cannot find the answer thou…
I am on the Mapping potentiometer value to the servo value part.
Question: When I turn the potentiometer (the analog input values from 0-1023), so it’s PWM output value exceeds around 165, it makes a click noise within the servo case then makes a rattling sound which suggest it is unstable. I tried to find some information within the data-sheet references which the book briefly mentioned in earlier on projects but no real luck. I have a few thoughts but no real solid explination.
Is this because the parts are just cheap ones/defect? why does it make a noise after going past digital 165? (the value is which feeds as the angle of teh servo motor)
