The next stage of the process involved connecting the picaxe project board to the protocircuit. The protocircuit is powered via the project board’s 4.5v battery pack.  A positive and ground is wired to the protocircuit from the project board. The four switches that connect to ground will be replaced with out- put pins 4,5,6,7 from the project board. Out-put pins 0,1,2,3 from the project board are connected to pins 6, 8,9,12 of the four digit display.  Now I know this circuit works I can start designing the layout of my PCB . It also allows me to start experimenting with programming.
