Using a simple Arduino board, a KS0108-compatible graphical LCD and our favourite method of reading many buttons using only one analogue input pin, Noriaki Mitsunaga has built a respectable home-made digital oscilloscope. Although you won’t be analysing high-speed data buses or complex radio signals, following the project is worthwhile as you can learn about the concepts behind how an oscilloscope works and more advanced Arduino programming. Here’s a demonstration of the project at work:
Well done Noriaki or should we say ‘yoku dekimashita’. For more information, schematic, Arduino sketch and more, visit the project page here. And we’re on twitter, so follow us for news and product updates as well.
So if this sort of project intrigues you and 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:
