Hello Athanasius!

Thanks for the reply and the write up. There is no delimitor such as "-", ":", "," and so on it is white space..and the photo resistor sends the following to the serial monitor: Light - 235, 226, 212, 256, 280 every one second and this is an ever changing number and like wise if it is Dark - 345, 332, 389, 367 every one second when the photo resistor is covered. So that is why I need to capture a range of numbers for light and dark so the lights will either be turned on or turned off....and it is always 3 digits in length.
