In today’s automation world stepper motor and servo motor are two most commonly used motors in embedded systems. Both are used in various automation machines like robotic arms, CNC machine, cameras etc. In this tutorial we will see how to interface Stepper Motor with ARM7-LPC2148 and how to control speed of it. If you are new to ARM7 then start by learning about ARM7-LPC2148 and its programming tools.
