[nmdonsk]

Hello! please tell me, could you write a very light version of uniter for Arduino or ESP8266, creating functions, using functions, arrays are not deep, variables, while and foreach, if and else, what do you say, is this possible? If you can, it will be just a holiday! Thanks for the project, I constantly use the library in my projects and for education.
