Got any suggestions on which other starter kits might be worth checking out? Is the Arduino kit a fairly solid way to go?
I think they're all much of a muchness, and as I say the Arduino one has its own forum. I think the boxes turn into components too?
In any case, any extra things you decide to get are readily sourced. No kit will have "everything" and one day you'll wish there were two of "these" and you never used "that"..... whichever kit you get.
If you don't already have one, get a multimeter. Here's
a lengthy discussion about price and brands....
