 Initially the aim is to just get some numbers displayed on the four digit seven segment display. I have decided to use the 4511 seven segment driver/decoder, picaxe 18x starter pack, four digit display and a protoboard. The idea is to use the picaxe 18x project board to drive the 4511 BCD and the display. The way this will work is by programming the picaxe, which will then send high(1) and low(0) code to the 4511 four inputs a,b,c and d, the 4511 then converts the binary code to seven out-put pins, which drives the numerical display.
