Normally a potentiometer has 3 pins? So, can I use it as a simple pot and if yes how to wire it to the arduino?
I just want to control the speed of a stepper motor and thought this speed controller could do this. But it seems it is not the right tool for the job....
I just want to control the speed of a stepper motor...
Why not just use a potentiometer?...R
I am using an Uno, cnc shield mwith a A4988 driver and a 17 hS13 motor.
I don't want to change the speed of the motor using the code, but want to be able to change it while it is in operation using a potentiometer.
That is completely illogical.The only thing that can change the speed of the stepper motor is the program code. And the program needs to read the position of the potentiometer and then figure out the interval between steps to create the speed you wish to operate at....R
I just realized that the cnc shield on top of my arduino is blocking the analog-in pin for my potentiometer.Is there a way to connect somewhere on the shield and get the arduino to read that signal?
