Making your own test equipment is an interesting learning experience, and a new example of this has been documented by Instructables member ptorelli and their logic analyser. This is an interesting twist on the usual analyser as it is a combination of Arduino-compatible hardware and a web browser, which uses HTML5, Node.js and Javascript.
The resulting device can sample four channels - or less with a greater memory depth. The software stack is an interesting combination however an explanation and required code is provided so you can recreate your own. Finally the browser interface resembles that of more expensive commercial solutions:
For the complete details to make your own version, visit the project's Instructable page. And for more, we're on facebook, Google+, and twitter - so follow us for news and product updates as well.
If you need to add external hardware or devices to your next Arduino project, you'll need a protoshield to mount the external circuitry. In doing so, consider our range of ProtoShields. From the tiny LeoStick to the Mega we have a wide range to suit your application.
