If you want a simple and easy introduction to stepper motors, check out the [IMSAI Guy]’s short video where he designs a very basic stepper motor controller and packs in a lot of quick lessons ...

With this circuit, you can use low-torque, low-revolutions-per-minute stepper motors in systems in which you formerly needed dc gearbox motors. By changing the pushbutton to a dpdt switch, you can ...

Bipolar stepper motors offer a simple way of achieving position control and accurate speed actuation without the need to close the loop through shaft encoders or similar means. To improve performance, ...
