Arduino Applications and Programs

Hi to one and all. over the last 5 or 6 months that I have been involved in RMWeb, there have been many productive and interesting discussions about Arduinos and their applications, including stepper motor driven traversers and turntables, and signal / point control. I promised to post some sketches (otherwise known as programs, source code, etc.,) and rather than have it in different threads, I thought I would start a new topic, and add pointers to the threads where relevant. I hope th

Ok, so something to report. The project has gone on far longer than anticipated for a couple of reasons, but has now taken a concrete step forwards. I originally set out to build a network of Arduinos in order to control the point motors, turntable and lighting dimmers from my control panel, without running out of connections in the 2 metre, 25-way,D-connector lead that I had. i had already arranged Arduino control of the turntable, using a separate mini panel with 2 LED
