# JUNE Challenge - suggestion - Binary ADD calculator

• ### General discussion

• Here is another suggestion , for June Challenge of the Month.

Last month, we build a binary clock, and a binary decimal converter.

To go further, i would suggest a kind of a program with 3 rows of binary LED display.

the top: the number in input

the middle: the number to Add.

the bottton: the results in binary

here is a link to start: Addition And Subtraction of Binary Numbers

• Nice representation of the LED-Arrays !

With a little improvement in the sub led_display(), you can repeat the input by other numbers.

```Sub led_display
f=0
r=0
For N = 1 To 3
For binary = 1 To 8
If x[binary][N] = 1 then
If N=3 then
GraphicsWindow.DrawresizedImage(orangeLEDon,50+f,100+r,50,50)
else
GraphicsWindow.DrawresizedImage(greenLEDon,50+f,100+r,50,50)
EndIf
Else
GraphicsWindow.DrawresizedImage(LEDoff,50+f,100+r,50,50)
EndIf
f=f+60
EndFor
f=0
r=r+100
EndFor
EndSub```

Extended Challenge for better understanding of a digital computer:

Calculation bit for bit with carrybit like a real logical binary adder and sound from relays.

• This is my solution for this challenge: MWQ039.

Use [1] to [9] and [0] keys.

• This is my advanced version of the Add Binary Machine, what's new in this version:

went up to 8 to 16 LED machine

red LED, computer music simulation while computing the BIN-DEC numbers.

a reset button to start over a new addition.
