One of the projects we are working on is Turnout Control. Most home layouts are using Atlas or Bachmann track with solenoid type turnouts like the one shown here. More professional layouts use slow moving motors like the Tortoise. Our goal is to make these turnouts controllable with an arduino, so that future projects using train detectors and DCC can allow more automation. So here is the beginning of our project. This one uses the above Bachmann turnout (arduino servo control article coming soon), a arduino nano, two IRL520 MOSFETS, two resistors, and two diodes. The schematic is as follows:
