Having a view of ADRXS150EB -a gyroscope ic i found it to be impossible for me to go ahead.after getting suggestion from Morli sir i start learning about all theorotical part related to armature uav and plan how to start that of mine.with previous some usefull knowledge i will be using atmega 128 along with gps(which gps i had to use i still had to decide) and accelerometer ,gyroscope and pitot tube (for air speed measurement and altitude.)as told earlier gyroscope and accelerometer r used for flight stabilization.likewise if we want to turn the plane to reach another co-ordinate we had to have some yaw movement along with roll.and we had specified servo to move for the required action .gyro and accelerometer will check the action taken by servos and will produce a error signal if required amount of action aws nt taken.on the other way i we want to have a straight flight, readngs of gyro and accelerometer must be constant.now how will i programe a code using accelerometer and gyro reading is a big question for me.we had to add gps ,pitot tube reading along with earlier reading to have a autopilot code.basically i m a electronics student doing engineering and presently in 3rd year.now use of PID loop is understood to me but i hadnt done any practical over it,so it will create a problem for meI had planeed to do programming in steps1)first i will program fr a simple turn using gps only. for checking whether my thinkin is right or nt.2)then i will prepare a auto take off code using pitot tube and gps.i will increase the amount of PWM signals to pitch servos and will increase the trotel rate slowly slowly after every 5 m or with a delay of 5 sec.. that will be a test.3) lastly i will use gyro and accelerometer.i want to knw that whether i m on right way or nt bcz earlier morli sir had broked all my fundas.i still had lot of question to be asked and i will keep on tryingthanks in advance.
