The application software drives the platform by instructing the Robostix to
sample the sensors' readings at predefined time intervals. Each reading is then
time-stamped and together with a GPS reading logged onto the storage unit. The
program also controls the LED boards to light up the necessary number of LEDs
reflecting the intensity of the measurements. Each sensor has a dedicated LED
board which reflects the changes in the sensor reading in real time.
