N-Scale Cantilever Crossing w/gate
thingiverse
This is an N-Scale automated cantilever grade crossing. THINGS YOU NEED: 2 pieces of IR Infrared Obstacle Avoidance Sensors Arduino Nano (or Uno) SG90 9g Micro Servos Flashing circuit 1/8" OD brass tube 0402 or 0603 prewired SMD red LED Watch Video from DIY and Digital https://youtu.be/UjHyxW2hHfg I changed the IR sensors into "break beam" by removing the emitter diode and wiring it across three tracks. I changed the original DIY code but still have problem with the gates raising to quickly. The sensor board is housed in a line side enclosure (Box for sensor). You will have to drill a small hole in the brass tube to insert the wires from the side flasher. I white-glued a printed paper with with red stripes for the gate graphics, and blackened the raised letters of the crossbucks.
