So late last week and early this week, I was in Sydney with the family. We were looking at places to rent in inner Sydney for my son. I recon I walked close to 30Km over the 4 days on which we were there. We also caught some busses, trains and trams. Alas we did not find something, but later this week, he looks like he had found a nice place near Glebe. It might be either a bus, or light rail to work, but he could walk on some days – and certainly walk home on some days to save a few bucks and also get some exercise.
So focus now turns to moving back to the first cut of the testing program, with just 5 IR detectors wired up. Once this seems to be working, I will switch over from a Arduino UNO to an Arduino Mega and continue the testing. I will spend time working on the inputs from the various switches on the control panel and interfacing these with the Arduino. Another rabbit hole that will throw a spanner in the works is testing my Arduino LCD screen. This is a 20 character x 4 line screen. My plan is to test writing text to it, and then incorporate some messages to the screen if the Signalman does something stupid, I can inform him. That could be something like throwing the points for a crossover or a siding without first setting the signals to stop first.
I am also thinking of having a self-test on the control panel where every LED is exercised before the Arduino gets into operational mode. I might also write messages as to what we are doing/testing as we go through the process.
