Autonomous with sonar and colour vision

[Wyspar]

I have the analog sonar vi called to see if something is less than or equal to the value given to back up for 1 second.

I am just wondering is this the right way to do this because I tested this, and it did not work.

I have the colour vision processing.vi working with the camera feedback to the dashboard, but I have tried to write and read if it saw a colour.
