I made a simple 8-bit adder using npn transistors for logic, an adapter for making the 230 V from the power outlet to 12 V, and some resistors to adjust the circuit electric needs. I have 16 buttons(8 to input 1 number, 8 for 2nd number). The transistors process this numbers and sum them and I output the sum to 8 leds. I want to output the result in decimal system and I found this 7 segment displays. The problem is that I need to think how to light the seven segments to draw digits based on the 8 binary digits represented by on/off leds. Is there any 7 segment display that take 8 inputs(binary digits) and do the computation needed to light the 7 segments, because I think I can't find the logic to convert the binary to digit segments:
0000 - ABCDEFG
0001 - ABCDEFG
0010 - ABCDEFG
0011 - ABCDEFG
0100 - ABCDEFG
I found a tutorial that explains how to do that, however I am not that advanced and I can't understand it yet, so I need a electronic circuit that does the conversion on numbers for me.
