I'm trying to power a tower MG-996R servo with this universal AC power adapter for an arduino uno project. The adapter can output: 3V/4.5V/5V/6V/7.5V/9V/12V.Output current:1.2A, also has a USB port:5V 2.1A.
I tried using the adapter with the 5V setting, but nothing happened. When using the USB port it worked but caused the motor to move sporadically (and burned one motor out - which is why I'm on this forum). Any idea what may be the issue or another recommended approach? Thank you!
