void Red(int Red) {
  arduino.analogWrite(5, Red);
    println ("PWM Red is " +Red);
}

void Green(int pwm_g) {

I'm always interested in inconsistencies. Why does one function have an argument named Red, while the other function that does the exact same thing, except for which pin it operates on, take an argument with a completely different name?

Personally, I'd have used redValue and greenValue as the argument names.
