I want to be a complete nerd and make a very simple binary calculator.
It will be two rows of 8 switches, each switch representing a bit, so a row is a byte (number), the two rows are added together, and a row of 9 LED’s will display the result in binary.
Is this possible to do with a picaxe microchip?
If not, what could I do it with?
Cheers,
Nick
Your problem would be data input/output lines. The basic idea is trivial in any microcontroller, but it’s the number of input/output pins available.
You might want to look into several shift registers (one per row and one per output) so you can marshal the bits in on a single pin or two and out on a single pin.
Specifically:
