I think it can be usefull for someone !
to install the plugin just follow this steps :
copy and paste the UE4duino folder to a folder called "Plugins’ u should create it in you own project folder “Documents/Unreal projects/name of your project”.
This is amazing, I’m definitely going to check this out in the next few days. Will it work with i2c and different types of arduino boards? I plan to try this with a lattepanda
