  1. Hello, was wondering if you knew of any sketches for a dual blade semaphore? I’m new to arduino. I do have 2 servos, a board but lost on the sketch writing part. Any help would be appreciated. Thank you!

    • I’m sorry but I don’t have anything that would be specifically for that. However, the general approach should be the same as for turnouts: setup your servos so that they will move the semaphores, then define a range of motion that gives you the movement you want — say from 60 to 120 degrees, or whatever is appropriate. You could then use your (or mine on this site) turnout code to run the semaphore. Different object, same motion and timing problems.
