Here, we describe a microcontroller-based propeller display that displays any messages sent to it from a personal computer's super terminal. In addition, the temperature sensing IC (TMP125) is mounted on the propeller display to display the temperature in real-time. A circuit diagram is a graphical representation of an electrical circuit that employs either simple representations of parts or industry standard symbols. The use of symbols is determined by the audience that is examining the graphic. This temperature regulated relay circuit is a basic yet extremely precise thermal control circuit that may be utilized in automation applications.
