This is a calculato i have been working on. At the moment it is very basic and can add up to a sum of 15.
It uses 1 seven segment display, a binary to hexadecimal to seven segment decoder, and 4 full adders which actually do the adding of the binary numbers.
The only downside is that ATM any number that is displayed that is over 10 is in hexadecimal so 10 actually appears on the display as "A".
Im still working on getting keypads hooked up to the adders and hopefully add in subtraction but it isnt working so well. I may add more displays in the future but that would require a complete over haul.
I will provide a like to the world and a schematic file when it is finished.
I will also include a like to a schematic of the full adder i used and a schematic of the binary to hexadecimal to seven segment decoder
I would like to give credit to scjoiner who showed me the basics of making a calculator and explaing how it works.
