Product Review
This book provides ideas for the model railroad enthusiast to develop automated signal projects. Most of these projects are HO scale, however there is one G scale semaphore signal. It also provides the basics on using and programming the Arduino micro-controller. These projects are great starting points for projects that specifically fit the model railroader’s own system.
