Your code only sends a "1" and never a "0". Maybe you'remissing an else?
Images of code are useless, how are we supposed to copy that to the editor if you have a more complicated problem? Please read How to get the best out of this forum and pay special attention to how to post code.

Hello whiter0se
Run some tutorials for the hardware selected and that in real hardware.
If you are happy with the results of the tutorials you can merge these to your project.
Have a nice day and enjoy coding in C++.
