Also, I didn't see in your photos earlier if you were using a mosfet or a transistor to power the servo. If that servo is drawing 250mA, you'll eventually kill the arduino. It can only do about 50mA sustainably.

Just my two cents. Loving this project. I've been thinking about something similar for my FIT for a while. I was thinking of using a rotary pot mounted to the dash to control the servo position. It's a bit more manual approach but I suppose I just like fiddling with things as I drive.


That looks like a great alternative. Thanks for posting. I'll look into it further.

As far as powering the servo, it shouldn't be a problem. The power for the servo is coming off the voltage regulator on the arduino board, not off the atmega chip. The voltage regulator is said to be good for up to 800mA.
