I. Summary The core concept behind the project and its circuitry involves incrementally rotating a stepper motor by a specific step angle. To accomplish this, the project will employ an ULN2003 IC in conjunction with the L293D Motor Driver. This combination is necessary because the controller lacks the capacity to supply the current demanded by […]

This instructable will show you how to control stepper motors (Unipolar OR Bipolar) manually with a knob, without the use of a PIC or PC, so no programming is needed. The position of the knob determines the position of the motor shaft, which will stay in that position until the knob is turned again. The

For another project I started I needed to control the motion of a stepper motor. A stepper motor is used when precision control of movement is needed. With each movement of the motor, the drive shaft steps a precise amount of distance (usually a few degrees with each turn). You can often salavage steppers from
