MobaLedLib

Arduino library for controlling LEDs and other components on a model railway.

New: Languages / DCC Buttons / LED preview / pyProgGen / Port detection / EEPROM / Switches / 4 LED Channels / Variables / ...

Excel user interface to configure the LEDs without programming at all improved by the engagement of Pattern_Configurator and Program_Generator!

To start the excel program press the Win+r key together and copy the following line into the "Run" dialog and press enter: %USERPROFILE%\Documents\Arduino\libraries\Mobaledlib\extras\Prog_Generator_MobaLedLib.xlsm

The use of RGB LEDs offers fascinating possibilities for lighting a model railway:

  • Infinite number of lighting effects - Brightness and color of each LED can be set individually and dynamically
  • Easiest cabling - The objects (houses, traffic lights, ...) are simply plugged into a multiple socket
  • Extremely affordable - 100 LEDs for the price of three "normal" lights
  • Up to 256 RGB LEDs (768 channels) can be controlled by an Arduino
  • Controlling other components is just as easy
    • Sound modules
    • Servo and stepper motors
    • Charlieplexing light signals
    • Power devices
  • Additional module to read 80 and more switches with 10 signal wires
  • Stand-alone operation or networked with other components possible

The lighting and some additional functions are controlled via the WS2812 / WS2811 chips. For this, only a single signal is required which is forwarded from one chip to the next. This makes the wiring extremely easy.

A lot of examples show the usage of the library. They could be use as startup for own programs.

This library is described in detail here:
https://wiki.mobaledlib.de/doku.php
https://www.stummiforum.de/viewtopic.php?f=7&t=165060&sid=e3b7f6122766c330d04cecf18b7b4878

Several videos which demonstrate the library are available in the following pages in the forum You could also search for MobaLedLib in the internet.

ATTENTION: Always use the actual Arduino IDE (Old versions 1.6.x and below don't support the directory structure used in the library examples)

Installation from the Arduino IDE: Sketch / Include library / Manage libraries Type "MobaLedLib" in the "Filter your search..." field Select the entry and click "Install"

Installation in der deutschen Arduino IDE: Sketch / Bibliothek einbinden / Bibliothek verwalten "FastLED" in das "Grenzen Sie ihre Suche ein" Feld eingeben Gefundenen Eintrag auswaehlen und "Install" anklicken
