Fly-by-wire throttle control with Arduino

 As part of a larger project, Arduino forum member "rameses32" has created an electronic throttle control for a stationary engine. Using a Freetronics Eleven as the base, the throttle butterfly is controlled by a PWM signal that is set by the user via a potentiometer. Furthermore to reduce the possibility of variations in the selected throttle position, a closed-loop feedback system has been implemented by having the Eleven monitor a throttle-position sensor to keep things in check. You can see the explanation in the following video:

An interesting use of our boards and of the Arduino platform in general - and a very simple demonstration that would help explain electronic throttle systems to beginners. For more discussion and the sketch, visit the Arduino forum. And for more, we're on twitter and Google+, so follow us for news and product updates as well.

If you're new to Arduino, the first step is a solid board for your projects - our Freetronics Eleven - the Arduino-Uno compatible with low-profile USB socket, onboard prototyping space and easy to view LEDs:
