Long time lurker. MRVP has a fantastic 2 part tutorial by my favorite contributor, Gerry Leone, on Arduinos. Had no idea it was so simple and easy to build, compile, and install.
Noticed quite a few topic and comments about Arduinos here in General, and also in Electronics. Figured more would see this here.
Check out: How-to-Library: Arduinos in Model Railroading - Parts 1 and 2. You'll be glad you did.
