Once again engineering student Rui Santos has published an interesting Arduino tutorial, which covers building a very simple oscilloscope. We realise that this won't give you the most accurate piece of test equipment - however it's a fun way to learn about Arduino and especially analogue inputs, as well as working with processing on a PC. Great for beginners, cheaply monitoring analogue sensor outputs or showing off to someone that you're encouraging into the world of electronics. Check out Rui's demonstration video below:
Well done! To recreate your own, visit the project page. 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:
