Beschreibung
Zusammenfassung:	An oven controller having a microprocessor for a microwave oven has a first dial for entering time cook data in one embodiment and time or temperature cook data in other embodiments and a second dial for entering duty cycle power data. Analog signals are derived from the dials which are converted into digital signals for entering into the processor using either discrete components, separate integrated circuits or the microprocessor itself. A servo mechanism is shown in one embodiment to rotate the dials in a prescribed manner to display cook data in either time remaining or actual temperature. In other embodiments a digital display is used to provide this information.
