Question 3: The relay used here wether it's 80mA (as said in the tutorial)or 200mA (as said in one of the posts) uses too much current for the arduino Uno: max 40 mA (or 20 mA sustained I forget where I read that), and therefor needs an external power source like a 12V AC adapter. Simply connect the contacts and the relay is switched on after a specified period of time. There is a 2-pin screw terminal for an external 12vdc to power the relay. Although the circuit shows the buzzer being powered from 12V, the circuit allows any buzzer that operates from about 5V to around 24V to be used. PCP SHOT 9,123,979 views.
