I am having a strange problem with my JRMI or my Arduino DCC++ system, I can operated a loco with the thortle just fine but I can not change the address and every time I read a page it fills it with a bunch of "123" in each field. any suggestions>?

Speed Matching question here.

Again I am totally new to this DCC++ stuff and JRMI as well as Arduino. So is it possible to make up a circular program track and place a sensor at each 90 degrees of that circle, so a total of 4 sensors and have work as a speed odometer and feed that back to JRMI to adjust the loco speeds automatically to a set speed curve? and could it work in both directions?

In the process of building my DCC++ system for the On30 portion of my future O scale layout. I am going to control the system with JMRI over ethernet. Currently I am using an Arduino Mega with ethernet shield and motor shield. I have ordered a proto shield to make the jumpers for the motor shield, so they can't come loose and also for future expansion. ThenDCC++ sketch is uploaded on to the Mega and is ready to go. All that is left is to test and add the proto shield like I said.

Just and FYI for those who don't know. If you plan on connecting DCC++ to JMRI via ethernet. If you have to use an Arduino Mega.

2 channel IR detector boards are now available. Ideal for a level crossing or a speedometer project.

Has anyone here tried setting up an Arduino with DCC++? Looks pretty interesting and not overly difficult to do.

For the Charleston Area Model Railroad Club, We have combined our train detector circuit from the scale speedometer project with a LED Crossing Light to make it simple to indicate a train is coming to a crossing. The next step is to add a servo operated crossing bar, and bell sounds, but I'm getting ahead of myself. http://arduinotronics.blogspot.com/2017/01/model-railroad-crossing-lights.html
