My nybble servo number 12 suddenly stopped working yesterday. There seems to be no problem with the servo itself. Because when I plug the servo into the 8th connector, the servo moves. Probably the problem occurred on the NyBoard side. When I connect the servo to connector number 12, it stops working. In this case, does my NyBoard need repair? Is there any way to repair it by myself? Or is there any other good solution?
I am always grateful for your help!
There's a moduleTest.ino in the repository. You can upload and run the code following the prompts in the serial monitor. The first one is a test servo section. If you find that one servo can rotate on one pin but not the other, then it should be the problem of the servo.
For brushed servo, the most frequent failure is on the brush due to friction and sparks. I have a post explains how to fix this kind of problem. https://www.petoi.com/forum/hardware/double-the-lifespan-of-brushed-dc-motor
