Hello first time poster here and I'd appreciate any help.
The Situation -
I've built a basic servo controller with these components:
-Regulated 5v power
-A capacitor before and after the regulator (electrolytic and ceramic)
-One NE555 timer
-A timing capacitor (ceramic)
-A diode (for draining timing capacitor)
-I couple resistors and a pot to select pulse width
I have a scope so I was able to set up the pulse range from 1ms to 2ms which is what is needed.
The Problem -
Jitter is the problem. The pulse width varies just enough to make the servo jitter, so I need to have a more accurate pulse width. Any idea's on improving the accuracy of the pulse width?
NOTE: The jittering seems to oscillate, this is reflected in the scope reading as well. Also the servo and controller are connected to the same 6v DC source.
