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.
