Hello,
I have been cracking my head thinking of ways in which i could use my Aruino Uno in my high wing trainer.. I just have the Uno and no other shields.
I could think of some basic stuff like mixing, LEDs, etc... want to do something with more utility, advantage (and coolness  ) ..
Cant get any good ideas.. Any inputs?

How about auto pilot? There's loads of info on diydrones.com. But that would require shields...

I have reserved auto pilot project for a better model(when i get one(not motivated enough to build autopilot for a classic sport 40 trainer which has already crashed once ))... and yes, dont want to buy any shields as of now
