When I published my previous tutorial, about building an accessory decoder with Arduino, many of you wrote me asking if it was possible to improve that simple code and implement a “real” turnout decoder, with more than one outputs.
In today’s episode, I explain the most common actuators that are available to control a model turnout:
- solenoid actuators
- DC motors
- servos
and how to interface the first ones with Arduino, using relays or MOSFETs.
In a following tutorial, I’ll also cover the 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, I shared the project on PCBWay.
Enjoy the video!
