I have seen many ways of doing it, but I need to keep the costs down. The EB signals change to red/red once the train reaches the EB Mast sensor, or when it has cleared the EB Signal sensor. I think I can use an IR LED and receiver and read that HIGH/LOW level with the Arduino. Now, I assumed that the chip I had was 0. I have an end to end model railway with 5 blocks and 4 signals. You'll probably also need sensors to tell when the whole train is clear of the crossing, as trains are of indeterminate length and speed. It was WAYYY OFF. Compute the scale speed of a passing train from the relative timing of DETECT conditions on the two sensors. It has a unique layout that allows easily plugging in things from IR sensors to servos, so I can use the same board as a DCC decoder/controller as well as being a sensor in an S88 or loconet bus. Your idea of an Arduino in every train won't work. However, if you can get a Raspberry Pi up … Oct 5, 2017 · The value of the pull-up resistor is not critical; 10K would be O.

I can be used for the following: Block occupancy detection: These 'sensored tracks' can be installed in sidings and yard lines to detect whether the particular track is free or not. Display the computed scale speed. See the double sensing page for details. Its frequency is about 8-10kHz and the peak to peak voltage for H0 scale is 28V. One sensor set = one IR LED + one IR phototransistor receiver. The Arduino can then send the correct DCC message to the track. So instead of a switch, the IR sensor would detect light and turn on the blinking lights. I presume that means that the user who wishes to run several locomotives has to implement some form of what model-railway-folks call cab-control. IR Break Beam Sensor - 3mm LEDs | Adafruit ADA2167 | Core Electronics Australia ) vs proximity sensors? Or vice-versa? One of the possible deployments is outdoors and needs to be able to run in daylight & night & be weatherproof. For applications where the speed of detection is not crucial, ordinary Hall Effect sensors like 44E can be used. So I added a reverse loop at each end of the layout to allow the train to make its journey between two points on a single track in both directions without having to move backward.
