A while back I bought a Arduino Uno and never found a good enough project for it until yesterday. I found a simple Logic Analyzer project. Sadly it isn’t a all-in-one unit. You still need a PC to control it. The project is called Arduinolyzer.js. It was a pain in the butt to get NodeJS working in Windows XP. Yeah I know I’m running XP but this is on a old system I use for tinkering. Anyway, after I fixed the broken Windows Installer I was able to install NodeJS just fine and within minutes I got a functional PC controlled Logic Analyzer.
