Stepper Motor Forward Reverse and speed control using Potentiometer and button in Arduino mega 2560 -.Control speed in real-time stepper operation as your required speed with sensor and button to direction changes...-

arduino mega to control stepper direction and speed

download our free Arduino stepper control code and read the code carefully, then read all pins where to connect in our case steps pin is 8, direction pin is 9 and enables pin is 10 and potentiometer input pin is A0 (variable voltage signal) respectively.

how its work.

. first, upload the code into Arduino or Arduino mega then need to connect all connections than on power supply and increase speed first using a potentiometer to start operation then toggle button to change direction .you also used sensor instead of a button.
