What is the voltage across the servos power leads while it is clicking? Make sure the servo negative power lead is connected to Arduino GND. Unfortunately, I don't have an RC receiver at home where the scope is. Something's obviously different, but I can't figure it out. I can't figure out why the TowerPro servos won't work with this arduino setup, but work fine in an RC receiver. 8-2.5 mSec pulse (based on the pot position) every 20 mSec. When looking at the signal on a scope, it looks great. I had a 220 ohm current limiting resistor in line with the signal to the servo, but have also tried without this. The grounds are in common for both the arduino and the servo. I am powering the servo separately from the arduino using an adjustable voltage bench top supply capable of supplying 3 A. So something is apparently wrong with my setup at home. I took the TowerPro servos to a local hobby store and they were nice enough to try them out in an RC Car receiver and they worked fine. I thought that perhaps the TowerPro was broken, so I tried another TowerPro with the same results. I tried using a lower torque Futaba servo that I had and it seemed to work fine. When I hooked one up, the servo just clicked (at about 3 Hz) and didn't move. ![]() I needed a high torque servo for my project and ordered several TowerPro MG958 servos. To simplify my tests, I'm currently using the Servo library Knob demo (adjusts servo position based on voltage input from a pot). I don't think the problem is with the arduino code, but I would appreciate any insights at all. I'm attempting to use servos with an arduino for the first time and I'm somewhat stumped at the moment. ![]()
