What is the mean of data equal 2 ??

[@RoboticaDIY]

you can put any values, but according to our code it means we have pressed FAN ON button in app.

good video,,,, computers have a long way to go before they are useful without a lot of code,, i can just turn on a light without saying a word.

when i try to compile code. then there is showed compilation errors..

[@RoboticaDIY]

may be you are doing something wrong in code, what error you are getting? If code is correct then check your port and board (Go to tools > board/ port)
