Sorry for cross-posting, I tried to reply to my previous post but got a notification that the announce list is not for discussions (makes sense), so I'm sending a new email.
I just made a few corrections to the servo motors project of a tutorial on Arduino and Pd I wrote last month (attached).

this is very nice ! i have one (beginner) question, for analog inputs ,if you push your potentiometer full right, couldn't it harm the card because it is a kind of short ? would it be better to have a resistor in serial?

I have to admit that my knowledge on electronics is non-existent. I've built quite some controllers with Arduino though, and never used any resistor with potentiometers and nothing weird happened, they work fine... I know that when you spin a potentiometer full right or left, it connects its middle leg to 5V or ground, but never had problems with it. Maybe someone who's got knowledge on this could clarify it...

If you want to measure the potentiometer voltage, you would define the pin as input. The inputs can stand this voltage as it is not higher than the supply voltage. But for your peace of mind you can add a resistor (1 kohm range) in case the pin is defined as output.
It is different of your Arduino is a 3.3V type like the Due... These definitly do not like voltages above 3.3V.

Let's say, you connect the left pin of the poti to ground, the right to 5V and the middle one to the analog input. When you turn the poti fully right, it creates a short between 5V and the analog input, which is no problem at all, as the analog has a very high impedance, which means only a very tiny current is flowing.
