Thanks. I updated the code and the post to reflect tests for the bridge case as you mention. It affected the 12 piece and 16 piece solutions. The animated gifs are udpated and should be correct now.

Thanks for the name, I found the article here: http://blog.jgc.org/2010/01/more-fun-with-toys-ikea-lillabo-... . However, he only solves for 16 pieces. This post and program solves for any number of pieces.

Good points, and I agree about understanding minimal simplicity and you don't need an OS and several layers of abstractions to blink a light. The post wasn't explicit (I think it is now after updating), but the intent was to demon

that is interesting, not sure if it is any easier than compiling some of the examples I provide, but it does open Linux platforms to those that know wiring, thanks.

It wasn't clear in the original post but this was really meant for embedded Linux platforms that already have GPIO mapped via SysFS so assembly wasn't considered. I've updated the front matter of the post to reflect that. I d

Writing a boolean type to SysFS/GPIO from NodeJS doesn't quite work so I tweaked your example to following similar pattern of the other languages. Thanks.

This is my favorite comment :-) After years of programming in enterprise Java, I failed to truly make it enterprise worthy! I'm going to see if I can get an assembly example added per your other comment.

It is a little more than that as you also need to write alternating state to the file, but you are right, and that is the point of the post. You can read/write embedded sensors/actuators in whatever language you are comfortable by
