Week 13 - Group assignment

We did some serial communication using the SoftwareSerial.h library, and getting inspired by the code provided by Adrian Torres on its documentation.

We were observing the information exchanged in the meantime in the real Serial monitor (from two different computers). We managed to observe the effect of the serial communication between the two arduino unos (lighting up the leds) but could'nt see consistent values in the serial monitors (probably a problem of format / byte).
