// fan_test.pde

// This is a test program to see if we can read the RPM speed of a PC fan.

// To set up, the fan should have an independent 12V poer supply, and the

// fan's SENSE techiometer pin should be connnected to the Arduino's pin 2.

// The RPM is sent back via serial (over USB).

void setup()

{

// set up interupt 0 (which is pin 2) and turn on the pull-up resistor as we

// would if the pin had been set to be an input. This is so that when the

// switch on the pin is open, it is not a floatin signal and has 5V across it

// (albeit through a high-resitance resistor to heavily constricy the

// current).

attachInterrupt( 0, rpmCounter, RISING );

digitalWrite( 2, HIGH );

// init serial comms

Serial.begin( 9600 );

// display fan speed. We divide by 2 because the fan's "sense" pin actually

// pulses twice per revolution. We multiply by 60 because fan_rotations will

// have counted the number of rotations in a second and we want RPM.

// Serial.println( fan_rotations );
