I am techie dad - do software for a living. Got a load of littlebits kits to play/learn with my daughter including The Avengers kit, the space rover, music and a number of the hall of fame kits. Before I start to make projects with my daughter, I wanted to test out the capabilities of the system myself. I'm very impressed .. just one niggle and it might be my error. In the avengers app, it seems I can go into a scratch like environment and program code onto the BLE bit. This seemed amazing except there was no way to have a variable in the app. I tried Android and iOS .. both versions of the app don't support variable (as far as I can tell). Am I missing something obvious?? Thanks!!
