In my search for some more awesome music-related Arduino things, I found Miditones and Playtune. Miditones takes a MIDI file as input and outputs a C array that you can copy/paste into your Arduino code and play it using the Playtune library. I just used the example code for an Arduino Nano, with pins 10, 11, and 12 going to three different speakers.

I didn’t realize until just now that the comment in the code says that you can wire all three pins to a terminal of one speaker, but I guess having three speakers makes it kinda surround-sound-ish. Maybe I’ll upload some more videos with a single-speaker setup or with a piezo buzzer. Anyway, here are some videos of Vocaloid songs being played with the Arduino.

Spent the past few hours making this flash game based on DJ Max Technika. Specifically, the song “In My Heart“. It was originally just fanart, then I decided to make it interactive by having her look at your mouse cursor, then I wanted a thing that dynamically generated bubbles (I based it on the code found here), but then I thought it’d be cool if the bubbles were notes instead. Then I was all “Hey, let’s make them clickable!” and then after that “Might as well make it a game.”

Instructions can be found by clicking the button at the bottom. SWF can be found here, and embedded in the full post.

Edit: Updated to include a sound and an star-explosion effect upon a successful click, also the ability to press T to toggle outfits. The previous version can be found here.
