Arduino is an electronic open-source hardware. It consists of a micro-controller. There is also a software to programm the activity of the hardware. As it is simple, based on an open-source community, Arduino can be used by anyone interested by electronics for a wide-range of applications. Their website is there.

The first idea of our project was to use an Arduino for the electronic part of our prototype. Actually, we use the Arduino as a energy source for the led, and, for the second prototype, we use it to gather informations given by the photoreceptor. Hence, we do a very little use of Arduino compared to its wide possibilities. Actually, we make the whole analysis with a computer, but a mid-term goal would be to use more Arduino in order to get rid of the computer and have directly a result from the measures.
