A Cost-Effective Approach to the Design and Implementation of Microcontroller-based Universal Process Control Trainer

This paper presents a novel approach to the design and implementation of a low-cost universal digital process control trainer. The need to equip undergraduates studying Electronic Engineering and other related courses in higher institutions with the fundamental knowledge of digital process control practical was the main objective of the work. Microcontroller-based design and implementation was the approach used where only one AT59C81 with few flip-flops were used for the whole eight processes covered by the trainer thereby justifying its low-cost and versatility.
