‘This code was already redeemed’

Each kit is only valid for one activation. New kits can be purchased in the Arduino Store.

Please contact us if you think there’s been a mistake.

‘This code doesn’t exist’

Make sure you’re entering the code from inside your kit.

The activation code consists of 24 alphanumeric characters (0–9, A–Z). It does not contain lowercase characters. Take special care with the following:

Zero	Capital O	One	Capital L	Capital I

Nothing happens when clicking Register

Make sure you’ve entered the full code (24 characters, excluding dashes).
