Need beginner help for a Raspberry Pi Project. Are there any step by step guides?

I want to first send some simple data to multiple virtual pins so i can view it on my phone. I’m having problems trying to figure out how to program on the raspberry pi. is there any good step by step guides out there that shows you how to program something like this? Everywhere i look its just arduino tutorials or more advanced raspberry pi tutorials that only show snippets of code.
