Abstract
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.

Summary
The basic objective in process control is to regulate the value of some quantity which means to maintain that quantity at some desired value regardless of external influences. C and Okezie C.C (2007) stated that a process control is typically a sequential logic system whose control algorithm can be represented in the form of a flow chart called an algorithmic State machine (ASM) chart [3] or in the form of. The ASM chart is a diagrammatic description of the output function and the nextstate function of a state machine to implement an algorithm and becomes part of the design documentation when completed. Electronic Engineering and other related courses in higher institutions with the fundamental knowledge of digital process control practical was the main objective of this work. The design approach used was the use of Algorithmic State machine (ASM) charts State Transition Diagrams (STD), State.
