then need a Common ground, signal to their respective pins.5

VCC can leave Not connected state if you have another power source for arduino.

Hi cool16yash.

It is great that you decided on making the flight controller yourself.
I have a made three flight controllers now, twice using the arduino mega, and once using nano.
And each time, they have worked great!

So were you successful with yours?
Upload a picture, I'd love to see.

Now, as far as your problem is concerned, I can't really say anything unless I know what have you one.
Please explain your wiring and upload a few images of your setup if you can.

set acc_hardware = 1
If you think it is correct, raise the motors to <10% throttle and CAREFULLY check that all the motors are blowing air downwards.
