The circuit in this Design Idea drives low-power, unipolar stepper motors using only a shift register, a few resistors, and low-power transistors. Adding an inexpensive 4053 analog switch allows ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

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 ...
