Model Train Detection And Action

MTD2A is a collection of user friendly advanced and functional C++ classes - building blocks - for time-controlled handling of input and output. The library is intended for Arduino enthusiasts without much programming experience, who are interested in electronics control and automation, and model trains as a hobby. The library support parallel processing and asynchronous execution.

Common to all building blocks are:

• They support a wide range of input sensors and output devices
• Are simple to use to build complex solutions with few commands
• They operate non-blocking, process-oriented and state-driven
• Offers extensive control and troubleshooting information
• Thoroughly documented with examples

Arduino Lint has suggestions for possible improvements to https://github.com/MTD2A/MTD2A:

Linting library in MTD2A
WARNING: A commonly misspelled word was found in the library.properties paragraph field. Suggested correction: Simple,  
         efficient and user friendly non-blocking building blocks to read sensors an activate diffent devices (servo,   
         relay, sound, LED etc). 16 PWM timed mathematical motion curves. Support parallel processing. DEMO videos:
