Hardware Support: Using Arduinos with JMRI

Using JMRI Features and Tools with Arduinos. Arduinos can be connected to almost any electronic component used on a model railroad, including turnout motors, turnout relays, led lighting, and a wide variety of sensors. You can, for example, define a sensor within JMRI that is identified with a CMRI input bit and a turnout identified with a CMRI ...


SMA28 JMRI Sensor Channels – Direct Arduino to JMRI ...

Sep 06, 2018· The Arduino then sends a sensor update message in 2 bytes at 19200 baud to JMRI which then updates the appropriate sensor, matching the sensor number received from the Arduino with the user defined name like AR:54.


IR Sensors

Dec 01, 2016· The original idea was to embed the sensors in the track bed. The sensors are fairly small and fit nicely between ties. The one chosen have a detection range of 215 mm, which would be ideal to detect when an engine truck passes over the sensor. The IR reflective sensor used are TCRT5000. The Vishay spec can be found here.


JMRI Model Railroad Interface / List jmridevelopers Archives

Again, I really like CTI, but would only use it for sensors plus outputs, not just sensors but to help others make an apple to apple comparison (or should I say Vista to Vista comparison :)), CTI with IR sensors would run about US11 per sensor for 64 (using a module called the Watchman and an Acela interface to JMRI).


Current Sensing and Occupancy Detection for DCC – The N Scaler

Jan 19, 2017· All ADC’s will produce some minimal reading for a sensor even when the sensor is not producing a signal. This is a form of noise that has to be filtered out. Also, some sensors (such as the ACS712) produce a signal in the absence of any current to measure — this too is noise that has to be filtered.


Adapting commodity IR sensors to actually be useful ...

Apr 08, 2021· First of what I hope will be a series of posts about using IR sensors to detect train location and direction. The goal: use JMRI''s VSDecoder location settings for blocks and a 5+1 sound system to produce fairly realistic movement of the sounds around the layout. Obviously doppler is missing, but for my simple needs and modest budget this will do.


Setting Up NCE Macros Using JMRI | Train Control Systems

JMRI supports the ability to activate Macros through a computer interface with an NCE command station. ... Create a Route called IR:NCEM:. ... Attach the Conditional to the Logix instance. Attach the Sensor to the Conditional as a Conditional Variable. Attach a Conditional Action to the Conditional to reset (inactivate) the sensor ...


jmriusers | Sensor input control of track power

Sensor input control of track power scripting sensors. I am wondering if anyone can give me some advice, my young grandsons and I have a small layout, JMRI installed, block detection, switch and IR sensors all set up and working. We have a lift up bridge, to save my knees, with track running over it, I have fitted a switch to the baseboard ...


Train Detection DCCWiki

Train Detection can be divided into three broad categories by location accuracy: Block detection whether a train is located somewhere on a particular section of track, or block. Location detection whether a train is located at a specific point on the layout. Proximity detection whether a train is located at or near a point on the layout.

JMRI sensors for DCC++ Railways of Germany

Apr 11, 2020· When the train goes past the IR sensor on exiting the tunnel, the whistle sounds. Basic but fun! I have more sensors on order, and will be setting them up so JMRI does various things when trains are at various places stations, sidings, ramps and so on.
