    I need a setup that will enable a Piezo 12V buzzer/alarm to be triggered to sound after a given time. This is not going to be hooked to any other device. I will need the Piezo to sound 2 hours after set. What are my options? I am a novice with circuits, but would be willing to make a project out of this if there is a solution. Thanks very much in advance!
