Hi There,
Please remember I am a beginner so a lot of the above is beyond me.
So what I can do is list all the components I used and the code (see below).
Then if you would be so kind as to look it over and see if there may is an issue
with the configuration and make any possible suggestion to get it working.
At present I have a chicken coop ready and waiting!

//This section is for initializing things:
