For my DT A level systems and control project I I making a 1/10th scale robotic arm to lift a car wiring harness. I am using a stepper motor but unfortunately my teacher doesn't know how to program one. Below is my circuit wizard circuit and program.
The problem that I am having is that the stepper motor, if in the forward position, controlled my a potentiometer (section 1 on circuit diagram), instead of pulsing forward, it does 3 forward and 1 back, this also can be seen in the photos attached where the stepper motor moves between position 356.3 and 248.8. Maybe the pulse sequence is incorrect?
I have also attached my model to show you what I hope the Robotic arm shall hopefully look like.
Any suggestions or solutions would be extremely useful.
Many thanks
Chris
