Experimenting with load cells and Arduino

If you've been wondering how electronic scales work, the following may be of interest to you. Arduino enthusiast Christian Liljedahl has demonstrated how to use load cells - the device that changes electrical resistance relative to the weight upon it - with an Arduino in order to convert the measurements into useful units. Christian has made the circuitry quite simple, using a Wheatstone bridge and a simple instrumentation amplifier to measure and amplify the changes in output from the sensors. 

It's a simple example, however could be used as the framework for your own measurement devices - so visit Christian's website to learn how. 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 and want to join the fun, 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:
