Arduino Uno code for controlling two PWM fans

	#include <TimerOne.h>

	// PWM Pins
	#define PIN_FAN1_OUTPUT_PWM 9 // PWM Signal to fan 1 - OUTPUT FAN
	#define PIN_FAN2_OUTPUT_PWM 10 // PWM Signal to fan 2 - INPUT FAN
	#define PWM_MAX_VALUE 1023 // maximum value of analog pwm throttle signal

	// Set these to the defaults that you want on startup (0-255)
	int pwm_value_fan1 = 220;
	int pwm_value_fan2 = 0;
