+   This basic example just shows how to read the output value of a infrared sensor. In this case we used the sensor avaiable on amazon link
+   we want to read the output value as a digital signal , so we can use the InterruptIn to better control the bot.
+    WARNING: it's necessary to calibrate the ir sensor, using the little trimmer on the pcb whith the sensors.
+   To calibrate the sensors run the other program
