If you love music but also enjoy working with electronics, this could be the project for you! Instructables member helenbang has created her own musical stairs.
As you walk up and down the stairs different notes are sent to a synthesizer on your computer. Each stair contains a sensor module which includes an IR sensor which allows the Arduino Uno controlling the project to know which stairs are occupied and which notes to play! You can watch her attempt to play happy birthday on her musical stairs in the video below:
This is a really fun project! To get started building your own musical stairs check out the full instructions, including code samples, at the following link.
If you are looking for an Arduino board to power your musical stairs why not check out the Freetronics “Eleven” Arduino Compatible Board.
The Eleven is just like an Arduino Uno (and 100% compatible), however the Freetronics team have made a number of improvements to the Arduino Uno design such as adding in a prototyping area, using a micro-USB connector and many more. These improvements mean that the Eleven is as easy to use as possible and is of the highest quality! To find out more about the fantastic Freetronics Eleven check out the following link.
