The project illustrates the use of a PIC microcontroller in creating the stepper motor controller by sequencing the steps, along the with TIP120 Darlington pairs for the switching circuitry, and a ...

Check out this inventive use of an MCU and stepper motor by one Alan Parekh. This great looking gear clock tells the time in a unique way. A PIC 16F628A microcontroller with an external 20MHz crystal ...

The project illustrates the control of two unipolar stepper motors using this circuit in full step mode through the RS232 serial port of the PC. The signals from the serial port of the PC is being ...

Stepper motors are now being used more frequently in industrial environments. Increased performance and reduced size make them increasingly attractive, and their application is no longer limited to ...

Here's a simple algorithm that uses conventional microcontroller blocks to control commercially available H-bridges to properly commutate a bipolar stepper motor through a microstepping profile.
