in the meantime the servo will start doing all kinds of craziness due to undocumented behaviour of the servo.write() function for position values >200.
Nope. No craziness until you reach 544. It's even written in an accurate comment. Not that I ever trust comments.
void Servo::write(int value)
{
if(value < MIN_PULSE_WIDTH)
{ // treat values less than 544 as angles in degrees (valid values in microseconds are handled as microseconds)
if(value < 0) value = 0;
if(value > 180) value = 180;
value = map(value, 0, 180, SERVO_MIN(), SERVO_MAX());
}
this->writeMicroseconds(value);
}
