Help needed selecting a chip for my project

[james1204791]

I have constructed a transmitter and a receiver using simple modules. The transmitter has four inputs which are displayed on output pins at the receiver. I need a chip that can display differing high pulses depending on which output pin is activated. For example output pin1 high gives two short pulses (ths could be used to give two short LED flashes), output pin2 gives two longer pulses, ouput pin3 gives one long constant pulse and so on.

I'm quite a newbie at this and was wondering if it is possible to buy ready made chips to do this chip or would it involve some programming? If it would involve programming how easy or difficult would this be?

Any help would be greatly appreciated.

Thanks,

James

James,

There are many ways to do this. If it

This is similar to a pulse counter.Try finding a pulse counter circuit diagram.Do some modifications if needed.

James,

I was thinking something like this.

Ante,
That's nice, then James can see the display blinking to the pulses. But you don't know if the receiver can give enough power output.
C, H and L? How about 2, 3 and 4?

James & audioguru,

Ante,
Sure, that's real cool, man (or bloak, or mate!).

Ante,
Sorry, but The Rolling Stones were on my radio. ;D
No disrespect.

Ante, good suggestion and nice clear schematic. I do not think you misunderstood.

I was not sure about it.
I hope it can help James.
