Design and implementation of a control system using AVR microcontroller

Nowadays, the intelligent appliance is becoming an integral part of the smart home. In this paper, we adopt AVR microcontroller atmega64 and relevant signal process circuitry to design a control system, which is used to control the intelligent toilet. After an overview of the hardware and software design of this control system we analyze some detailed design. A series of conflicts encountered in the course of implementation are listed in the paper. With the resolution of these issues, this system has been implemented to control an intelligent toilet with high reliability and practicality.
