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,

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

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

This project is for the class ATLS 3300 at CU Boulder. Push buttons can make buzzers sound. Five buttons represented the tone C, D, E, F, G. There are two modes. The switch determines the mode and LEDs can indicate which mode we are in. In mode-1, the game handle can determine which buzzer sound.

Goal of this project: Convert a cheap toy piano to work as a midi device and use it with Synthesia (http://www.synthesiagame.com/) Other programs that use midi inputs can also be used. Approach: The pushbuttons of the piano are used to make a simple pull-down circuit for the arduino mega. The arduino interprets the keystrokes and
