Make posted the tutorial for this fun doorbell project. We’d love to see other customizations of the project!
Next time you host a party, wouldn’t it be great if your guests could choose what kind of entrance to make? The Make-an-Entrance Party Doorbell lets them do just that. It’s a wireless doorbell that has four buttons. Your guests can select between themes you choose, say, royal fanfare, heavy metal, Star Wars, or cheering sports fans. When they push the appropriate button, a regular doorbell sound is heard inside. But when the door is opened, a sound effect is played to match their selection.
At the core of the project is a Raspberry Pi equipped with the EnOcean Sensor Kit. This kit is neat because it allows you to use wireless sensors and buttons that don’t require batteries. For example, the kinetic energy exerted to press the doorbell button will be used to send a wireless signal to the Raspberry Pi to play the doorbell sound effect. And a solar-powered contact sensor attached to the door will signal the Pi that the door has been opened, prompting the Pi play the appropriate sound.
And of course, this project is customizable — choose your own sound effects to match your friends’ tastes or your party’s theme.
