Mods, I sent an email to the US store and Arduino support but haven't gotten an reply back yet.
I ordered a Uno Starter Kit but decided to not purchase one yet. I am pretty sure it has not been shipped. Is there a phone number I can call?
There is no phone number. Contacting Arduino Store support via this form is the best thing you can do:
But hey, get that starter kit. You could have a ton of fun and learn a lot from it. The Arduino Mega I bought on a whim 7 years ago certainly changed my life.
