What Fingies is

“Fingies” is the name of a new integrated framework consisting of a webserver, an online administration tool and last but not least the central “Fingies” hardware component. The “Fingie” box comes with several pre-manufactured printed electronics cards with sensors (touch, light, temperature, …) and actors (led, loudspeaker, motor, …). “Fingies” communicate sensor data not only with each other via WiFi and the Internet – they can also stay in touch with your laptop, smartphone or other Internet capable devices no matter where they are.



We want to provide an easy to use prototyping tool for experimenting quickly with Internet of Things Applications. “Fingies” offer the possibility to develop hybrid systems with printed electronics and conventional electronics. Maybe even more important it will be fun to experiment with the “Fingies” platform in many different ways and to develop applications for local and global network applications ranging from games, art and design projects to more serious applications for monitoring environmental or health related parameters, logistics, etc.


Technical Setup

The “Fingies” Box is equipped with an Arduino Yún. The Arduino Yún is equipped with an ATmega32u4 microprocessor and an Atheros AR9331 - that runs a Linino Linux system. With the WLAN module onboard it already offers a powerful, networked computer - almost everything we wanted for our Fingies. For allowing the Arduino Yún to talk to printed electronics cards and to work as a standalone device we developed a shield that is plugged into the existing Arduino pins. Powerful magnets connect our shield to the printed electronics cards.



First Steps: The easiest way to develop first applications is to play around with the pre-configured set of printed electronics cards and the “Fingies Box“. 

Advanced Users: When you are more advanced you can develop your own printed electronic cards or other objects that can connect to our box. You will be able to work on the open source Arduino Code. A huge global community of Arduino programmers is ready to help you. You can develop Websites, Mobile Apps or other Webservices that communicate with other “Fingies” worldwide.
