how is this for a start?

i have put schematic , code ir controlled 12vdc fan , see if headed in right direction.  looking turn fan off , on not control speed.  sure symbols may not 100% correct can't fritzing @ work had cut , paste mspaint , code below.


ir receiver code

#include <irremote.h>

int recv_pin = 9;
int transistorpin = 11;

irrecv irrecv(recv_pin);

decode_results results;

void setup()
{
  serial.begin(9600);
  irrecv.enableirin(); // start receiver
  pinmode(transistorpin, output); 
}

void loop() {

  if (irrecv.decode(&results)) {
    serial.println(results.value, dec);

    if(results.value == -2094865891)
      digitalwrite(transistorpin, high);   // set fan on
    else
      digitalwrite(transistorpin, low);   // set fan off

    irrecv.resume(); // receive next value
  }
}

thanks input guys might have

do want momentary or on/off? fan works if hold down button.(not useful )

i have done ir stuffo n blog dduino.blogspot.com
