im having a problem controlling a stepper motor using a microcontroller..what i did is that i test it with my board coz it has led's to check whether its working or not..we are tasked to make a program in c++ that would make a variable reluctance stepper motor work. If you press the the R button the rotor of the stepper motor will turn forward (clockwise), if you press L it will turn backward (counter clockwise), and if you press S the program will stop.. so how would you be able to make a program out of this conditions?
