I need to make a loop keep running until a condition in the code is met to break the loop.
I was thinking of using a while loop like this:
while (Y<60); motorX_down; end while(Y>60); motorX_up end if (Y==60); motor_stop; end
I use this code to control my motors according to the feedback from the image processing. My objective is to make the camera move so that its center is the same as the detected object coordinate. I had the image processing part done and can get the detected object coordinate in X and Y.
Then arduino will move the motor to adjust the camera.
Now my frame size 160x120 with X:80 and Y:60 as the center.
motorX_up will make the camera move up. motorX_down will make the camera move down. motor_stop will stop the camera.
So far i'm only trying to make the camera move vertically only to test it.
But when I run the code, the motor move only down :( So maybe I thought I had the while loop wrong.
Because you never update Y in your first loop so it keeps going down. You need to update Y value in the loop, for example
Y = Some_function_to_generate_Y; while Y~=60 if Y < 60 motorX_down; else motorX_up; end Y = Some_function_to_generate_Y; end
