Need circuit to produce 3 modes of audible confirmation

[Jason S]

I need to make a circuit that will produce either one, two or three short
consecutive beeps depending on the input signal it recieves.
For example:

Input 1 = One beep (could mean 'ON').
Input 2 = Two beeps (could mean 'OFF').
Input 3 = Three beeps (could mean 'ERROR')..

This is just an example. The 3rd one is not critical, but would be nice.

I want to be able to add it to practically any circuit which will provide
audible confirmation of the circuit's current operation. I was thinking of
using a PIC to do this, but is last resort (as I know absolutely nothing
about them).

Has anyone got any suggestions?

Thanks.

Use a PIC. The learning curve will be worth it, and as you want to add it to

'practically any circuit' you will later appreciate the flexibility.

Tried Picaxe?
Cheap, and so easy even I can program them.

If you know nothing about PICSs use an AVR instead their chips are a
little
more flexible one good feature is 2.7v-6v operation - handy for battery
powered devices a hardware and software to program them is about the
same
price, (prebuilt/kit/diy)

No, i know nothing about PIC's or AVR's, but sound interesting! I guess you

could do almost anything with those from 1 chip.

some questions:

1 are the beeps to repeat or are they edge triggered?

well I was thinking once the required beeps have occured, then it should

stop completely until the input signal is removed - the only way to make it
sound again is to reapply the signal.

2 what if imput 1 activates after input 3 had activated
and sounded 2 beeps already?

arrgghh, good point. you mean like the signal slightly overlapping? not

sure. I will somehow make it so that the "new" input signal is ignored
until the previous beeping cycle has finished... like add a delay circuit.

Thanks, I'll definately consider it.
