The document describes a microcomputer-controlled breadmaking machine. The microcomputer controls heating resistors, motors for mixing ingredients, and a fan through digitally activated switches. An analog temperature sensor provides temperature readings to the microcomputer via an A/D converter. A digital timer counts down the remaining time. The control programs in ROM determine mixing, heating, and cooling stages. Users can select crust darkness via the keypad. The machine mixes ingredients, warms the yeast to rise the dough at 90°F, and bakes and cools the bread over about 4 hours as monitored by the microcomputer. Microprocessors now commonly control appliances, vehicles, and industry equipment.

3. Microprocesser-controlled Breadmaking machine?
 A microcomputer along with its timing circuit,keypad,and display
unit controls the heating resistor , fan motor , and bread-
ingredient mixing motor by means of digitally activated switches.
 An analog temperature sensor , through an A/D converter ,
provides the status of temperature to the microcomputer .
 A digital timer circuit counts down , showing the time remaining
in the process.

4. The control programs are showed in ROM and
determine when and how long the machine should mix
the ingredients and added to the bread pan ,when and
how long the heating resistor should be turned on or
off for various parts of the cycle ,and when and how
the fan should be on to cool the loaf after baking is
finished.
The parameters such as light , medium , or dark bread
crust are entered through the keypad into RAM.

5. According to the program stored and the parameter entered
the machine initially mixes the ingredients for several
minutes.
The heating resistor is turned on to warm the yeast , causing
the dough to rise while a temperature of about 90°F is
maintained.
The time remaining and the temperature are continually
checked until the baked loaf is cooled and the finished bread
is finally ready in about 4 hours.

6. Microprocessor and computers in
various forms are used extensively in
household appliances ,automobiles ,
and industrial equipment.
