3 tries, 5 seconds, or both?
I think you should only base this on time, not presses. Many people by default press a button more then once, as dumb as it is, it is just human behaviour.
Waiting 5 seconds is easy....just set up a 555 timer in one shot configuration (Google for the schematic).
Recording the voice is harder...easiest would be a tape recorder with a remote jack. |
