I was originally posting under the “Servo Controller” thread, but felt this next question would completely threadjacked it…
So I now have some life to my servo(s), using the PulseInOut module. However I’m seeing a lot of inconsistency and I think it has to do with the grounds. I’ve read that you should connect all grounds together. How should I go about doing that? Use a breadboard? There’s a ground on the module, but I’m also giving the servo power via an external 5v source (battery pack).
I was really hoping to throw some diagrams and coding together and submit them to GHI so you can post them in the catalog/developer part of this module, but I just got stuck on the easiest part. The hardware connections.
Here’s what I have at the moment:
Signal wire from the servo goes direct to the PulseInOut module, on the PWM pin 1(out).
Ground from the power pack goes direct into the ground on the servo ground connection.
5V power from the power pack goes direct into the 5V of the servo.
So I have an extra wire - the ground from the pulseinout module, which goes nowhere. And/or should I wire this differently?
