Hey, my HD-1440A microservo hasn't been behaving as expected lately, and I was wondering if you could help me diagnose it.
The servo inputs are tree wires; one yellow, one red and one brown. I have, for my test circuit, connected them as follows:
| Servo | Arduino | |
|---|---|---|
| Yellow wire | - | Gnd |
| Red wire | - | 5v |
| Brown wire | - | Digital pin 9 |
I then tried to run the "sweep" example that comes with the Arduino software. The servo went to its farthest counter-clockwise position and remained there. If I put my finger on it, I could feel it vibrating slightly.
Is there anything else I can do, or will I just have to declare it dead?
