Step 4: Safety and Considerations!

SAFETY:
When playing with AC, don't fool around.  You don't want to go blowing your breaker, or worse, receive one heck of a deadly shock.  When you are testing your device, make sure that someone is with you.  If you are young and inexperienced, talk with someone who knows more about electrical safety.

CONSIDERATIONS:
