Working on a school project that is due soon. I am pretty new to the Arduino. I am using the Mega 2560.
I am attempting to drive 4 ESC (electronic speed controllers) that in turn drive brushless DC motors. The ESCs have their own large battery power source, but to control the motors you need to supply a servo signal to them (as well as ground).
Here's my problem: I can't get all 4 working at the same time. I can get 3 working, but the 4th (let's call it D out of A,B,C, and D) won't work. If I unplug some of the others, then motor D will work but not the others (obviously).
The ESCs have 3 wires- signal, power, and ground. I have only been using 2 of the 3 wires (signal and ground) and this has worked fine for 3 of the controllers but not all 4.
If I plug in the Arduino 5V to even 1 of the ESCs, the arduino lights turn off and it's almost dead- I assume the controller is drawing way too much current.
Does anyone know how I can remedy this situation?
Thanks very much!
