An Arduino-Based Servo Switch Machine
A while ago, I was looking for a DCC controlled switch machine for my garden railroad. My switches are hand built with some Micro Engineering G scale turnout kits. The switches were originally built with hand throws for moving the points and activating a micro-switch for powering the frog. These have served for many years but do need periodic maintenance because of the outdoor environment here in Iowa. Winters can be hard on trackwork.
