Let’s Learn Together shows the most common actuators that are available to control a model railroad turnout:
- solenoid actuators
- DC motors
and how to interface the first ones with Arduino, using relays or MOSFETs.
The tutorial also covers two remaining types of actuators.
The source code for the examples and the files required to build the MOSFET board are available in a GitHub repository.
If you need already-made PCBs, the project is shared on PCBWay.
