/diy/ - Do It Yourself

>>1933441
i did a stepper controller with an Hbridge as a final prject as a proof of concept and did this in the arduino IDE as the function definition that is called to do steps

the speed and rotation direction is done by reading a potentiometer with a middle detent so if its left i one way and if its right of the deten its the other way with turning the pot more is faster

the speed is basically set with a delay and with more pot angle you get less delay in the main function (its janky and not really efficient but as i said its a proof of cocept and it works well)

you most likely messed up some wiring shit although i didnt really have a good look at your program
