This would be a neat exercise to follow as I have an Uno as well. However, I think it lacks the memory to handle the op

Really?because i think 32KB is just about enough for the quadrotor to hover and maneuver steadily. But it might not be able to do acrobatics maneuvering..

Does anyone know how to program the arduino 328 to execute stable hovering (VTOL) only??PLEASE---- (''-)

So far i've managed to control the motors directly via the TX and RX communication.But the UAV won't take -off!I guess i really need to work on the sensors and PID.

I've tried to read signals from the acc and gyro and it works.But how do i integrate this value so that the angular speed of the propeller can be controlled??How can i implement a PID controller??Enlighten me..

Check out the web site, AeroQuad.com.

That software will run fine on a Uno.  You're going to have to do some coding to get the code to work with you sensors. What is that green card in your diagram?  Is it the sensor board? (i.e. IMU)

Thank you..for your reply.But one question:why do they use logic level converter when the board can provide 3.3V directly?

Oh and the green card there is the hacked wii motion plus gyro sensor (ITG3205). I assumed ITG3205=ITG3200 in the coding. Is it right?

I think the Uno's logic levels are TTL, so you need the LLC to interface any CMOS sensors to it.  You'd have to look at the ITG3200 datasheets, but I think they are equivalent. You're better to ask all these question son AeroQuad forum.  They are very helpful there.  My username is 'elchan' on AeroQuad.  See you there!
