This example drives a JHD1313m1 LCD as found in the *Grove Starter Kit. This connects to an i2c buss.Light sensor from the kit connects to A0 socket and LED connects to D2 socket.

The code for Display(LCD) be used in either of two ways. By default, it will use the upm module. This is much the simpler way to drive a upm supported device.

The purpose of this is to demonstrate that multiple sensors in this case LCD, LED and Light sensor can work together. UseUpm is the main function which contains all the intilatization of different module and variables. It compares the lux value as it reaches to threshold value it switches on/off between LED.For scrolling long strings i.e.(length > 16) there are two functions scroll and loop which are resposible.The Values in the array are taken from *seed grove wiki page.

Now at the end Comparing all the lux values to display appropriate message on LCD.
