AR Drone 2.0 + 1Sheeld: Real-Time Flight Data Streaming to PC

About this project

Our project see the control of various flight data recorded by a smartphone and transmitted in real-time to your pc, like accelerometer sensor, gps position,noise drone, orientation, gyroscope and more.

We use two Arduino for data control,one mounted to the drone, and one to the computer, two xBee to communicate remote data of the 1sheeld to your pc.

A fun and easy way to take advantage of all the features and sensors of the smartphone, and also to take some nice pictures ;)
