Need to make a circuit to count number for pulses and display on 7-SEGs

[rallysteve]

HI there, I need to construct a circuit that is capable of displaying a series of 3-digit codes on a seven-seg display. The codes are communicated via pulses through a wire. So for example 1-2-3 would be pulse......pulse..pulse......pulse..pulse..pulse then a short pause before the next code. I can sort of see how I could do this with shift registers and timers but would like a compact solution if possible. I am not particually clued up on PIC programming and things but am keen to learn about them.

Any help appreciated

Regards Steve

If you want a more compact solution then it's time to learn about microprocessors. The learning curve can be a little steep to start, but is well worth the effort.

An easy way to start is with a microprocessor that can be programmed in Basic such as some of the PICs or a Stamp computer from Parallax. I have used a Stamp to control an LED with variable light duration and intensity, and read out the status on an LCD module.

Basic is relatively easy to learn and is a good language to start with. You can always move to C or Assembly later on if you want but those are generally more difficult to learn.
