Boolean for activation of a pixel on a sensor

[Natejk7]

I have a sensor that takes measures the thermal environment. It is a 4x4 pixel array. I have a working VI file that outputs values that was given to me.

I would like to add a light that shows if a each pixel array is being activated by radiation, so it must slow down the time delay for this to be noticeable. I have no idea where to start with this, I have the internal address of the voltage generated from each pixel, so I was thinking that if this is greater than zero then it would activate a light. I've been trying for several hours and since I am new I am struggling to get this working.

Do you want to pause the loop when a voltage is above a particular threshold or do you want the array reading loop to always run at the same speed but display the information in a way that allows the user to see what is going on?
