If you want a simple and easy introduction to stepper motors ... part where the source code is compiled and the 22V10 is programmed, and jumps directly into testing the circuit on a breadboard.

Stepper motors are useful in many consumer, industrial, and military applications. Some, such as personal-transportation systems, require precise speed control. Stepper-motor controllers can be simple ...

grbl is stepper motor ... included on grbl Arduino shields (or integrated Arduino+drivers equivalents), and so I have been considering designing my own to link to external motor drivers. The ...

Adding an inexpensive 4053 analog switch allows bidirectional switching. Compared with other simple stepper-motor-drive circuits, it has better-than-half-step characteristics (Figure 1).
