Hello,

I also have this type of adapter, although I stupidly threw away the packaging showing what way to place the plug...

Hello,

Im still not having any luck with Flowcode, most of the components cannot be registered no matter what I do...

Hello Steve,

I resolved the other issues on friday, but the flowcode missing component issue is my only current issue... I'll try some of the things you have said and report back...

Many thanks for all the support,

Another update:

I have made a program like this:
