Simple 2-bit Calculator with a decoder for a 7 segment display.
sorry, this is my first ever circuit that I ever made, the circuit on the above is not working just ignore it and only use the lower Circuit, good luck . . .
This is a 2 bit counter using d flip-flops that skips 0. The sequence is 1, 2, 3, 1, 2,... .
2 Bit presettable T-Flipflop (normal / reverse counting)
A 2 bit ALU
Two 1 bit adders are connected to produce a 2 bit adder
