I think that LIFA is really an awsome tool by allowing a unique GUI interface to the Arduino. I wanted to share this project that I did for school. It's a wireless electrocardiogram that uses 3 leads. Inside the black box, is the ATMega328 processor (what is found on the Arduino) with all the signal conditioning and a Xbee unit. The device measures 3.8" x 2.4" x 1" and is carried in a simple case attached to a pocket. The ECG signal is transmitted to a computer for LabView to graph. But wait there's more! The ECG is also saved to a database to be viewed in real time over a webpage or Android App. All possible thanks to LIFA.
Attached is a word document with device and program screenshots.
