Keychainino: a programmable, playful Key Ring

Based on Arduino, it performs electronic light games by piloting a LED matrix thanks to a special multiplexing mode. In the fast paced world we live, moments when we can do whatever we want are rare and we have to cut them out from our routine, by skillfully balancing between the busy schedule of the day. We are always so in a hurry that the only relaxing moments we have, could be the public transportation waiting time, or when we are queuing in a bank or at the post office. In these moments, people read a book, someone checks the latest Facebook or WhatsApp notifications, someone plays with the smartphone, and someone listens to music and meanwhile fiddle with keys or maybe with a click pen.”
