Hi, I want to control 6 servos with my Arduino Mega. The program is ok and I can control one of the servos perfectly. Since these servos are .5A each, I can only control one "Smoothly", so I used my phone charger (5V, 2A) To control 4 of them, and then I connected the 'control' cables to their ports on the Arduino, the problem is that none of these move, they receive the current because they go hard, but I can't control them, if I feed one of the servos with the arduino voltage, it starts working.

I don't see why this happens, could I get some help?
Thank you in advance! :)

Have you connected the ground of the supply to the Arduino ground?

Without seeing your code and your wiring diagram it is a little difficult to assist.

Have you the servo GND connected to the Arduino GND? (You should have)

...R
Two or three hours spent thinking and reading documentation solves most programming problems.

I am just using the arduino port, the supply cables of the servos are connected to my 5V source only, should I put the ground from my 5V source to the Arduino Ground?

I fixed my problems connecting both GND's, thank you!
