This text is a speedy introduction in datavisualisation. It is used as an introduction of a workshop for students graphical design and fashion. The aim is to give the students enough information to explore the possibilities of datavisualisation into their fields and to use the experiments in their collaborations.
This text describes way to play audio with microcontrollers, Arduino or stand alone Attiny45 or even smaller Attiny13a. The text starts with soundgadgets. It tells about 8 bit sounds, about Soundshields. In the end it will take a raspbery Pi for playing better quality sound and explain what you have to do with the Raspberry Pi to make it play soundfiles with an LDR activation.
