Johnny-five driving LCD Matrix or call Arduino library from Johnny-five I would like to know if it's possible to drive an LED Matrix like this one with johnny-five.
If not, how can i call Arduino library/code from johnny-five.

If I Write method on sketch into the Arduino, can I call them from J5 REPL?
After research, it can't be done, as J5 use firmata to drive the Arduino, the only way is to write a library to use with.
