This Paper concerned with the designing a low cost PID temperature controller. Because of their simplicity, robustness and successful practical application, PID controllers are the most popular and widely-used controllers in industry. Many PID design methods have been proposed, each has its advantages and limitations. However finding appropriate parameters for the PID controller is still not easy task. The objective is to achieving an important design compromise, acceptable stability, linearity and medium fastness of response. In this paper, Atmega128 has been used as a brain to the prototype. PID controller has been selected as a controller because it has faster response than the conventional on-off controller. The experimental result reveals that the PID controller can be implemented into the low cost prototype and able to control the temperature according to standard regulation.
