Stepper Motor Interfacing with 8051 Microcontroller – CodesExplorer

In this article we will be rotating stepper motor with 4 steps in clockwise and anticlockwise direction.

Stepper Motor will be connected to any one of the Ports. In our case we will be connecting it to PORT0 .

Please make a note that if we send 1-2-4-8 stepper motor will rotate clockwise and Similarily
8-4-2-1 will rotate anticlockwise.

Lets See the code Now…..
