An Arduino calculator I coded using a regular PS2 keyboard for input, and outputs onto a 20x4 LCD.

Can only do addition, subtraction, multiplication & division, and no decimals yet, but might add that next time I'm bored.

  • At 1:29 the screen seems a bit buggy :D

  • @Firestream lol, was waiting to see who picked that up first. The ant was actually between the LCD and the backlight, so I couldn't get it out :(

  • How do you handle Multiplication and Division? Can you share the code you use?
