DIY Arduino-powered Go Kart speedometer and tachometer

 In what can be described as a great use of the Arduino platform and a fascinating project, Arduino forum member "matclowes" has described his growing dashboard project for his go kart. After liberating a tacho and speedo from a motorcycle, they have been modified for use with the kart by having the needles set via PWM each from one Arduino - which receives pulses from the engine and rear gear sprocket sensors. As an Arduino calculates the RPM figures a "change up" LED has been fitted to aid driving performance and other indicators and functions will be added in the future.

Very well done, and shows what you can do with an Arduino and some spare time. For more information and discussion, login to 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:
