The map() function lets you take a value in one range and convert it to the equivalent value in a different range For example, mapping a value of 255 from the range 0 1023 to the range 0 100 would return the value 25, because 255 is one-quarter of the way along the first range and 25 is one-quarter of the way along the second range This is perfect for converting an analog sample to a percentage using a line such as the following: tankLevel = map(sensorValue, TANK_EMPTY, TANK_FULL, 0, 100); However, we also want to factor in the calibration values defined previously The actual sensor value will only vary between the TANK_EMPTY and TANK_FULL values, not the full 0 to 1023 range, so we substitute those values for the first range in the mapping.

So far we haven t figured out what the TANK_EMPTY and TANK_FULL calibration values need to be, but we ll do that later For now, just leave them at their default values tankLevel = map(sensorValue, TANK_EMPTY, TANK_FULL, 0, 100); The function then checks the URL that has been requested to see if it s the default page using a global variable called URL that is set by the WiShield library You could extend this function to check for other addresses and create subpages for your Arduino, but we only care about the default page with the address / if (strcmp(URL, "/") == 0) { The WiServer object has special print() and println() functions that work just like the equivalent functions in the Serial library, but instead of sending the values to the serial port they re bundled into the response packet sent back via WiFi.
