3 Bit Binary Adder Project

[durdur]

Here is the description

The program will request the user to input two numbers between 0 and 7 to be added together. Each number will be sent over the parallel port output pins as a 3 bit binary number to the 3 bit adder circuit.
The program will display a graphical representation of the sum as displayed by your 3 bit adder circuit. Depending on your hardware circuit, the sum will be displayed either as four LEDs or as a 7 segment display.

I decided to go with 3 bit adder instead of 7 segment display

Here is what i got so far

Turing:

var number1, number2 : real loop     put "Enter a number"     get number1     exit when number1 > 7     put "Enter another number"     get number2     exit when number2 > 7     put "The sum is " ..     put number1 + number2     %Makes 0 in binary     drawfilloval (100, 250, 50, 50, gray) % Circle 1     drawfilloval (250, 250, 50, 50, gray) % Circle 2     drawfilloval (400, 250, 50, 50, gray) % Circle 3     delay (500)     %Makes 1 in binary     drawfilloval (100, 250, 50, 50, gray) % Circle 1     drawfilloval (250, 250, 50, 50, gray) % Circle 2     drawfilloval (400, 250, 50, 50, brightred) % Circle 3     delay (500)     %Makes 2 in binary     drawfilloval (100, 250, 50, 50, gray)     drawfilloval (250, 250, 50, 50, brightred)     drawfilloval (400, 250, 50, 50, gray)     delay (500)     %Makes 3 in binary     drawfilloval (100, 250, 50, 50, gray) % Circle 1     drawfilloval (250, 250, 50, 50, brightred) % Circle 2     drawfilloval (400, 250, 50, 50, brightred) % Circle 3     delay (500)     %Makes 4 in binary     drawfilloval (100, 250, 50, 50, brightred) % Circle 1     drawfilloval (250, 250, 50, 50, gray) % Circle 2     drawfilloval (400, 250, 50, 50, gray) % Circle 3     delay (500)     %Makes 5 in binary     drawfilloval (100, 250, 50, 50, brightred) % Circle 1     drawfilloval (250, 250, 50, 50, gray) % Circle 2     drawfilloval (400, 250, 50, 50, brightred) % Circle 3     delay (500)     %Makes 6 in binary     drawfilloval (100, 250, 50, 50, brightred) % Circle 1     drawfilloval (250, 250, 50, 50, brightred) % Circle 2     drawfilloval (400, 250, 50, 50, gray) % Circle 3     delay (500)     %Makes 7 in binary     drawfilloval (100, 250, 50, 50, brightred) % Circle 1     drawfilloval (250, 250, 50, 50, brightred) % Circle 2     drawfilloval (400, 250, 50, 50, brightred) % Circle 3     delay (500) end loop

You need parallelput.
