Can I create a quadrocopter RC transmitter using an Arduino? http://www.instructables.com/answers/Can-I-create-a-quadrocopter-RC-transmitter-using-a/ http://www.instructables.com/static/defaultIMG/default.SQUARE2.png http://www.instructables.com/static/defaultIMG/default.SQUARE.png http://www.instructables.com/static/defaultIMG/default.SMALL.gif TylerT35 I recently started playing with a quadrocopter. I love it, but I am not a fan of the traditional RC transmitters. I believe that they were designed for older RC airplanes and I think the design could be improved upon. I have also recently started experimenting with Arduino. I bought a USB shield and...
