This problem is in concern of arduino

Write a program which will read in the CSV code and generate several things:

The mean and standard deviation for the Potentiometer readings

The mean and standard deviation for the Temperature readings

The mean and standard deviation for the Light sensor readings

A count of how many times each button was read as depressed

A line graph containing the pot, temp, and light readings over time with the linear approximation of each data set. The pot line should be purple, the temp line should be red, and the light line should be blue.

All graphs should be properly labeled.

Present this information in an obvious and attractive manner
