I'll apologise now if this is in the wrong place, but I couldn't see a newbie thread. Anyway, a while back I started looking into Arduino but have only just really had the time to start to learn about it. I've made a very basic project (http://www.instructables.com/id/Persistence-of-Vision-Wand/) which is a persistence of vision wand. It works fine, and if I want to change what it says I just have to re type one line in the code. The problem I have is that I've been doing some photography with it and have to take a laptop with my to change it. I have an iPhone and also use an iPad (please don't judge me too harshly!), and wondered if there a way I can change the code using one of those, perhaps by a direct cable link or adding Bluetooth to the project?
Thank you in advance for any help and advice,
