Design Considerations for Microcontroller Based Process Control for Washing Machine

This paper describes the design considerations of microcontroller based process control for washing machine. In this paper, AT89S51 microcontroller is used to control the process of washing cycle and to drive the external output devices such as water inlet valve, wash motor, water drain valve. The control strategy program for AT89S51 microcontroller is implemented by using assembly language. The objectives of this development are to design a simple control system using low cost microcontroller, to construct the functions of system using simple control system. The main abstraction of this research is to improve control and software systems of microcontroller based process simple control system in Electronics.
