So I'm trying to eventually use bluetooth in a project I am working on, but I want to begin by just the simple turning on and off of an LED. I have tried a multitude of set ups, code and apps, yet nothing has worked. I will link some of the websites I used below. I am new to arduino, however all of the code used has been just copy and paste as it's on the website. The HC-05 connects to my phone fine (with the light blinking slower when it does) and downloads the code fine. I am using a google pixel phone which if I am not mistaken, is an android phone. If anyone could give me some advice or something to try, it would be immensely appreciated.
