I am making an animatronic Wheatley from portal 2 and I am working on the eye lid movement at the moment. I have to eye lids which are about 8 cm across and are made out of foam. I am going to use two servos to move the eyelids.
I want to be able to control the servos at the same time, I will be using a 2 axis joystick to control the servos, but I will only use the up down motion to control the servos. I am very ignorant when it comes to this sort of thing. I am not sure what code I would need to write to control the servos using the joystick, could anyone help me with this? Any advice would be greatly appreciated :)
