A
seven segment display is the most basic electronic display device that
can display digits from 0-9. They find wide application in devices that display
numeric information like digital clocks, radio, microwave ovens, electronic
meters etc. The most common configuration has an array of eight LEDs arranged
in a special pattern to display these digits. They are laid out as a
squared-off figure ‘8’. Every LED is assigned a name from 'a' to 'h' and is
identified by its name. Seven LEDs 'a' to 'g' are used to display the numerals
while eighth LED 'h' is used to display the dot/decimal.
Here 7 segment displays are interfaced with atmel 89c51, Here we have connected only two 7 segment displays.
