Task 55 - Datalogging to an Array: Serial Monitor, software

The usual output: room temperature & my rather warmer fingers for the second (reset) group of values..
..had to re-arrange the software a bit, as the Comments in the software mention..



/* * Project: DataLogging_Thermistor_task_55_v2
* Author: Jane-Maree Howard
* Date: Sunday 13/06/2010
* Platform: Arduino 18
* Purpose: To data-log 10 successive readings from a thermistor at 1-second intervals, save the readings into an array called mySamples[] & output results to the SM after the last reading.
* Operation: The average resistance of the thermistor is about 10 kOhms, so it & the 10k resistor form a voltage divider, whose junction is inputted to Analog 0.
* Description:
* Connect one end of the thermistor to 5V, the other end to Analog 0.
Then connect one end of a 10K resistor from Analog 0 to ground.
This is quite similar to the photocell Task, but the software is a little different.
* Comment: I tried messing about with Functions - then after several abortive
attempts, decided to stick to the KISS priciple..

NOTE: this blogger doesn't like 'less-than' signs - it thinks they're HTML
thingies.. so where you see n"10 put n 'less-than' 10
(sigh)

// the thermistor and 10K pulldown are connected to a0

// this counts the readings to allow halting..

Serial.println(); // skip a line to start with

//first read in the 10 values..
for (byte n=0; n '' 10; n++)
{
// read value on thermistor pin i.e. analog 0
mySamples[n] = analogRead(thermistorPin);
// delay 1 second
delay(1000);
}//for(n)

//..then print them to the SM
for (byte n=0; n ''10; n++)
{
// print the analog reading to the SM
Serial.print("Analog reading = ");
Serial.println(mySamples[n]);
}//for()
