Lego train level crossing 10128 automated by Arduino

This video shows an automated Lego train level crossing set 10128. The barriers are moved by Lego Power Functions motors and powered by an L293D motor driver chip. The Lego train level crossing is controlled by a stand alone Arduino Uno chip. Please consider supporting me on Patreon: https://www.patreon.com/almightyarjen The barriers are activated by a sensor along the Lego train track which is triggered by the passing train. The barriers remain closed for a few seconds when the last wagon of the train has passed the sensor. This time is adjustable to the speed of the train or the distance between the barriers and the sensor. The barriers close pretty fast which looks a bit unrealistic. I've done this to prevent problems when I put this automated Lego set in a big Lego train layout. In case of a slower speed of the barriers, the sensor has to be further away from the level crossing. This could be two or three meters which isn't practical.

I sometimes automate Lego trains, or make a stop motion video or I just setup a huge Lego train layout in the living room. Do you have (reasonable) video suggestions? Please let me know!
