I made a quadcopter with an Arduino and all connections are fine. When I arm it, the motors spin without props but when I connect the props and arm it, the motors spin for a second and stop. Can anyone help? Why does it happen?

We need more details of software, motor sizes, props, overall FC set up, other components etc. Pictures might help too.
