chacky1234, I am in your same situation, only that I will use an arduino nano v3 as gstav in tek project
I follow all the videos of gustab, in this I answered the same to see if there is a possibility of a guide.
Please, create a guide with photos of the arduino nanano v3 and its components, with some connection scheme for clumsy, I read the juzi posts, but this one with the different chip, I would be interested in being able to do it like in your tek project that has a normal arduino with more connections, for example for the lights
