Arduino music.
Notice: this article is for linux based users. see also: http://computoman.blogspot.com/2015/05/arduino-music-starter-update.html The Arduino is one of the neatest microcontrollers. For something so simple, it can do an amazing amount of projects. One such project that interested me was the Digital melody project. If you have one the the Arduinos where the Atmel chip can be removed, you can make your own project without the board once the programming is done. For this project, all you will need is the Arduino, usb cable (for programming), computer, some wires, optional 100 ohm resistor, and an old eight ohm speaker. Usually the back of speakers on the magnet have what resistance they are. So grab the old dead radio or the like that has a speaker and see what it has. Old personal computers are likely to have one too that you can borrow for a minute. Now you need to build the circuit. It is minimal and you should be able to set it up quickly. Resistor adds safety for pr...
