This entry for the Project 14 project theme World in Motion documents a project I am currently working on. My hobby is creating animation in model railroad lay...en-USTelligent Community 12https://community.element14.com/challenges-projects/project14/theworldinmotion/b/blog/posts/pulse-width-modulation-a-speed-equalizerThu, 28 Jul 2022 00:25:21 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:f80eb1cd-c9c0-4d8d-a63f-da29c815f090robogary1<p>Very nice project idea. Not to get ahead of your ideas, but will the PWM be manually adjusted or are there plans to automate the speed based on position of the train on the track? For example, have the train slow down if a prox switch&nbsp;( or limit switch or IR detector) identifies the train is in the switchyard or approaching a road crossing ?&nbsp;</p><img src="https://community.element14.com/aggbug?PostID=24057&AppID=386&AppType=Weblog&ContentType=0" width="1" height="1">
