For this purpose external EEPROM is used. Microcontrollers are uses as automated devices usually. Microcontroller is a compact tiny computer that is fabricated inside a chip and is used in automatic control systems including security systems, office machines, power tools, alarming system, traffic light control, washing machine… Forexample, Intel 8096 is a 16-bit microcontroller. …well as the mechanical Door sensor, pressure sensor, keypad are also interfaced to microcontroller. One of the messages provides the option to enter the delay time. Whenever a particular mode starts RTC is initialized to zero and there onwards RTC is read and compared with the set timings; with the battery backup provision actual RTC can also be implemented. Drawback of this method of programming is that read value may not be ‘instantaneous’; it may be older by some microseconds or milliseconds. Keypad is connected to PORTD. Power supply circuits and regulators are not shown in the Figure (1). These pins are also used to RB5, RB6 and RB7. Microprocessors and their microcontroller derivatives are a widespread, if Figure (1) Block Schematic of Washing Machine Controller.
