I wander if this ESC could have the motor direction changed? What I mean by that is that could I rotate it clockwise and then counterclockwise?
I have tried to control the BLDC with the servo library and it looks like i can only control the throttle of it.
In my project, I will need to control the BLDC in both direction. Do I need to get another ESC or can I program the ESC in someway to achieve that goal?
You can only change the rotation by swapping any of the two wires on the ESC, unless it's an car-ESC that supports brake and reverse. If it's not intended for a car, you cannot change the direction of the motor by means of the servo control signal.
