/*
   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

DigitalIn ir(D4);// definition of the pin D4 as digital input


DigitalOut led(LED1);//definition of the green led on the board as digital output
