How to Make a Simple Doorbell
A doorbell, at its most basic, is a device that emits a noise when a button is pushed. You can make a simple doorbell from a few supplies purchased from a hobby store. A few supplies found around the house are also needed.
No expertise in electronics is necessary, although adult supervision is required if a child is making the doorbell, since a cutting tool must be used and there are exposed wires that can cut the skin.

Twist the exposed ends of the black and red wires coming from the 9-volt battery snap between your fingers. Insert the exposed end of the red wire through one of the two contact holes on the bottom of the push button switch. Wrap a piece of electrical tape around the contact.
