After we came up with the Bi-color LED Matrix Driver Module kit, we have been looking around for interesting projects to work with it. You may be interested in some of the projects we have put up at instructables using this LED Matrix kit. Instructable to build a Arduino (SPI) 7 Bi-color LED Matrix Scrolling […]

People love listening to music. It is as they say, music reflects our mood. And it is a spectacle to see music become ‘alive’ right before our eyes. Well, that’s what music visualization does. According to Wikipedia, music visualization “generates animated imagery based on a piece of music. The imagery is generated and rendered in

This sketch connects a voice call from your GSM shield and Arduino to a remote phone number entered through the serial monitor. You’ll need to attach a speaker and microphone to hear the connected phone and send your voice. First, import the GSM library #include <GSM.h> SIM cards may have a PIN number that

The Musical Table is a toy table that allows kids to play musical phrases by moving toys around the surface. Each of seven switches can play different musical phrases in four bases, making 27 different musical phrases in total. Some of the phrases are musically related and some of them are not. This toy

In this project, we will learn how to use a speaker (peizo sounder) and use switch button to change the pitch of the sound. Sorry about this one, you might find it a bit difficult to digest at first, and I didn’t realise it’s actually harder than it sounds. Anyway, spend some time on the code,

Jeopardy style quiz games are favorites for creating excitement and educational instruction at the same time. Teachers, summer camp counselors, and even industry educators find this type of game to help generate interest and involvement from the participants. The idea behind the game is simple, but sometimes finding a device that will perform the “first

So we haven been working on the new soundgraffiti board. This is an installation wich creates sounds using sprayed water. The connection is made with water. We used copper plates as our sensor. the plates had a cutout line in the middle of 0,1 mm. Once water hit this line it would connect both sides

O’K, after having some fun with stereo version of the VU meter I described in my previous blog-post, now it’s time to do a serious stuff. Studio grade VU meter !!! 24 steps, equally spaced every 3 dB, covering Extra wide Dynamic Range from -63 up to +6 dB. Single (mono) channel this time, no messing around,
Audio VU meter with Extra wide Dynamic Range 69 dB using Arduino Continue Reading
Beat Sync is a single frequency audio spectrum volume meter. It can isolate around a certain frequency ( I choose the bass ) and display it on a creative 8 segment LED bar graph. This is meant to be quite simple, yet allowing room for more difficult upgrades. It is built around the Arduino Open

My brother posted a video about this on facebook almost a year ago. Some old floppy drives playing Bach’s masterpiece Toccata & Fugue and it got me really interested. So I read about it when the author posted a how-to on his blog and did a couple of tweaking using SammyIAm’s Musical Floppy program when the project gained a
