Most doorbells just make a simple generic tone. But I thought that it would be fun to modify a door bell so that it has a customizable ringtone. That way you can set it to play music or custom greetings. You could make it to scream on Halloween and play carols at Christmas. So in this project, I am going to share with you how to add a simple recording module to a wireless doorbell.
Step 1: Materials
Wireless Doorbell (and required batteries)
9V recording module (RadioShack Model: 276-1323)
9 volt battery
Soldering Iron and Solder (optional)
Hot glue and hot glue gun (optional)
