Hello, new user here. Microcontrollers have interested me since I was young but I either had no money (when I was young) or school made learning microcontrollers boring (now). But after leaving school for half a year, I think I regained my interest in these and can afford it too. So I'm going to try to build a device for a start. I have some, not too much, experience with the Sparkfun Inventor's Kit when I was in school, mainly input/output, PWM, multithreading and stuff. I think I've forgotten most of them anyway.
I'm going to buy some components, I just want to check with everyone if I'm getting the compatible items. I can only afford to buy them once, as after I get them I'm going to fly off to another country for work (and bring the Rainbowduino along). I'm not sure if I can get more components shipped there.
The end product I'm aiming for would look like this:
