Tkinter: How to assign calculated value to a Label

[LoneStar]

I wanted to check Yoriz' suggestion as having helped me a lot. I wasn't using classes, so that's a step in the right direction. However, there's no button on this site to select the suggestion that helps (unlike in other forum sites, e.g., Microsoft Developers Network).

I added a reputation point to Yoriz, just to show my gratitude.

I haven't fully solved this yet. It's not posting the value to the label but funny, when I add a messagebox just to see if there's a value read from the sensor, the value is then posted to the label when I click the "OK" button on the messagebox. Obviously, I still need to work on this.

But I followed Yoriz's advise to create classes to make it easier and I'm getting there.

Thanks.
