This paper is about interfacing a stepper motor to a microcontroller-based board which is programmed to control the speed of a stepper motor in response to a coded input from the microcontroller board. It takes advantage of the microcontroller and its support modules to address the problem on a real-time implementation. A transducer may act to provide an electrical equivalent signal of a time-varying parameter such as temperature over a given range, which is digitized before fed to the microcontroller-based board.In this work, a microcontroller-based (using MICROCHIP PIC16F877 and a motor driver IC UCN5804) board is programmed to control the speed of a stepper motor in a response to varying digital input and is made to respond to properly to variations in specifications as well as to variations in an analog signal equivalent of a temperature transducer. The results of variations in step angle and divisor of a stepper motor on the preset value are reported.
