Digital Electronics lab report 1

1.Most interesting Arduino Project

1)The first one seems like a midi drum controller but instead of using launch pad, he used the recycle Coke can and cut it in to pieces to make look like a real drum. While you punch each part, the programing makes it sound like the exact percussion.

2) the second one is kind of easy. He used a keyboard with no sound connected to Arduino programming and make it sound like real keyboard. It is basically looking like a midi controller keyboard.

3) the third one is also like midi controller keyboard. But this time instead of using keyboard, he used Coke Can again to demonstrate the sound. While each time hit the Coke can, it makes different pitch just like when you press the keyboard.

All those three you can find it in these video.

1. 0:00-0:30
2. 1:38-2:05
3. 2:15-2:25

4)The forth one looks a little bit mind blowing to me. He used several disk player and connect to Arduino programming. And make them automatically to play the music. The program makes them to move forward and back and it composed as result of “the pirate”!

5)The last one is also a little bit crazy. They connect the old school typing printer to the Arduino program. While you type on it, it makes music and sounds really great!

You can find them in this video. They are the first 2!

2. 5 Most interesting final projects!

1)The first one is Nick Royall’s 8 step midi sequencer. I think it is cool because you can switch channel to play drums,808, or piano. I can imagine how useful this project can be because buying a real midi controller sometimes cost a lot of money. But this project shares the same traits with the real midi keyboard.

2)The second one is Sam Kingston’s LED cube with audio visualization. He built this device that connected to computer with programming, and the playing music actually can make the LED Cube lightening in different pattern. It looks pretty cool especially when you are having a party.

3)The third one is Samual Pachon’s midi sequencer along with LED light. While he plays on the midi sequencer. The LED light actually shows us different pattern. And it all depends on how fast, how slow you are playing. It is pretty cool.

4)This one I wanna talk about Mathew Lau’s drum midi sequencer. Although it looks pretty simple and easy, it is actually pretty useful for you to build one at home instead of buying an expensive one at guitar center or whatever. He basically make a physical drum pad and connect it to the computer with Arduino programming. And it works out as a drums midi.

5)The last one is Hank Boader’s project. He set up a device with pen and paper. Then when he play the music, the pen automatically draws the wave form of the music. Although I think it might not be really useful in producing music, it is really cool to see this brain storming project. And I think it is pretty difficult because you have to do a lot of coding in order to recognize the waveform of a music.

BRAIN STORMING!!!
