Request: How to wire a Firgelli L16P to an arduino Answered
If you followed my instructables you know I'm always building robots. I'm trying to assemble a Stewart platform using Firgelli L16P linear actuators. My problem is that I can't seem to get the Arduino PWM to talk to the firgelli RC servo interface. I have...
- 12v running to controller pins 1 (-) and 2 (+)
- arduino PWM pin 3 to controller pin 3
- controller pin 1 to arduino GND (for common ground)
and I'm running a version of the servo sweep example sketch, modified to run on pin 3.
The actuator doesn't move.
I've tested the control board with the PC control software from Firgelli (works) and I've tested the arduino with a TowerPro SG5010 I had lying around (also works).
Notice the controller LED will NOT come on in this configuration, but once I remove the common ground the light turns on.
So what am I missing?
