#### Simple Stepper Motor Control with Raspberry Pi

Stepper motors are a type of brushless DC motor that can be controlled so that they advance a fixed step size. Additionally, they provide a strong holding torque. This can make them useful in applications where you want to rotate the motor precisely without employing encoders. When prototyping, I...

If you have a circuit in hand, there are a dozen or so discussions online to determine the comparator’s characteristics: high threshold \$V_{TH}...
