CODE:
/* Serial output
This example shows how to print out values you may create in your running
program. This is useful to debug a program or to see what some intermediate
program variables are.
In the program below we first define some arbitrary variables. Some are
floating point, others are integers. In the setup section we establish the
so-called 'baudrate', which is the rate (bits per second) at which
communications will occur over the USB cable between the Arduino and
your PC. We also print out a heading. You put literal text between
parentheses, like "abcde".
In the loop section we first send the current value of the millisecond timer,
and then we send the 5 values. Notice that for the floating point variables
you can specify how many digits to show to the right of the decimal point. The
truncated values are automatically rounded up/down as appropriate. For the
integers the whole value gets sent.
Also notice that we send a comma after each value, so that the data can later
be easily read into a spreadsheet as a comma-delimited text file.
We then delay for 2 seconds, and do it all over again.
Note: Refer to the superSerial library for how to do serial input to the Arduino.

// put a 'carriage return' (newline) character at the end
delay(2000); // burn up 2 seconds
