Arduino IR Musical Stairs

Picture of Arduino IR Musical Stairs


This is a small scaled musical stairs! It was a project that had a deadline; had only two days to build it. So, it is a very small scaled project, but still serves its purpose! IR Sensor (receiver) that I used is TSOP38238 from Adafruit, and the IR LEDs are also from Adafruit. The little black boxes have the IR LEDs in them (made the boxes to help people avoid stepping on the LED), the sensors are all attached on different breadboards at the left end of the stairs. This has 4 active steps, one playing a single note on the piano. For this project, the notes are C,D,E,F, respectively from first step to the top step, and if you press the right arrow key on the computer (on processing), the notes all change to G,A,B,C, respectively from the top step to the lowest. Then, if you press the left arrow key again, the notes go back to C,D,E,F. So, even with these small piano stairs, you can play the whole scale from C to C (one octave)!

For some reason I read that as 'Muscle Stairs' I was expecting some kind of escelator. Musical stairs are way cooler.

I love it. I'll see if I can send you the videos I have of me playing with it since I think I only sent you photos.
