Firstly move your post over to other hardware (why can't a mod lock down this section of the site so that you can't post new stuff?) ... then check out a post I created a week ago https://teksyndicate.com/forum/other-hardware/pi-vs-arduino/179016 .... then watch this https://www.youtube.com/watch?v=7vhvnaWUZjE
