Refer the attached image,this is i want to do,measuring circumference of large shell.
For calculating this, im going to fix a sensor stationary and rotating shell, in this the sensor points from position say P0,now the shell rotates P0,P1,P2,sensor keeps tracking...After attaining the initial P0,the sensor stops,length is measured is that the circumference.
is this concept possible to implement?
i am new to arduino..kindly help.
is there any other method to calculate circumference of a big size shell?
