Driving Semaphore Signals with Servos (Video#55)

If you use a servo controller, you can typically adjust upper and lower boundaries of the movement as well as the speed in both directions. But of course, for true modelers (or rivet counters!), that’s not good enough.
Real semaphore signals have overshooting or bounce back and sometimes some hesitation in the middle of the movement. So it is no surprise that I got a request to add these features to my servo decoder. In this video I am going to show you the results and explain how I changed the Arduino sketch from Video #17 to make these nonlinear movements happen.
