Background

The human being is emotional, all our activities are influenced by our personal emotions. When we learn something new, when we talk with our partners, when we make business or when we take decisions our emotions are influencing and probably affect the final result.

For that reason the study of emotions is interesting and his outcomes are applied to several areas like learning, marketing or health (Harley, J. M., Bouchet, F., Hussain, S., Azevedo, R., & Calvo, R. 2014).

The study of the emotions using electronic devices has increased last years, there are many papers related to this topic called Affective Computing (Calvo & D’Mello. 2010).

Affective Computing is all related to study the emotions using tools like computers or other electronic devices. One of the problems in this area is the high cost of the sensors used to collect the electrical signals in order to detect emotional changes (Harley, J. M., Bouchet, F., Hussain, S., Azevedo, R., & Calvo, R., 2014).

With the rise of open source movement in both hardware and software have been developed interesting projects that lower costs and give access to new technologies and measuring sensors at reasonable prices (Santos Ribeiro A.,Salvado D., Evans G., Soares Augusto J. and Ferreira H. 2014).

Arduino is one of these platforms, basically it is a prototyping board provided with a micro controller and developed with an open architecture. This board was designed to make it possible to add "Shields" and extend its functionality.

A shield very interesting for the study of emotions is the e-Health Sensor Platform. The e-Health was designed by the company Cooking Hacks to allow researchers, developers and artists get measurements and data for biomedical research, testing or fun. This platform allows to get biomedical variables such as temperature, electrocardiograms, galvanic skin response or blood pressure, however this is not medically certified.
