Microcontrollers As Material


We�ve developed a set of tools and techniques that make it easy to use microcontrollers as an art or craft material, embedding them directly into drawings or other artifacts. We use the ATtiny45 from Atmel, a small and cheap (~$1) microcontroller that can be glued directly to paper or other objects. We then construct circuits using conductive silver ink, dispensed from squeeze bottles with needle tips. This makes it possible to draw a circuit, adding lights, speakers, and other electronic components.
