Make your own LED binary calculator

Fun LED binary calculator via Syst3mX writes –

You can’t calculate binary values “as is” on most handheld calculators and using the windows one is just a pain, so i decided to make my very own (binary only) calculator. This calculator supports all the basic functions like : NOT,OR,AND,XOR, addition,subtraction,multiplication,division and modulo.

So join me as we are going to enter the world of ones and zeros and play with some LEDs and switches along the way!
