Front Desk Service Beeper |
| Often a simple mechanical bell is used by a customer at a store or hotel lobby,
which when activated alerts the personnel that service is requested. The hobby circuit below performs the same function electronically.
It also contains a timer circuit, so the service beeper can only be activated once every 30 seconds or so. This prevents some impatient
person from ringing multiple times. |
