Chapter 5 - Issues with potentiometer

Hi all, I’m having some issues with the three potentiometers included.
In theory their values should range from 0 to 1023 but mine don’t appear to go beyond 670.

I’ve even tried to remove everything else and just leave the pot but same thing … it works fine but it maxes at 670.

Anybody else’s seen this?

Also they don’t appear to “click” too well in the breadboard making it a bit flaky to the touch …

670 indicates to me that you have a 5 volt Arduino and have the pot connected to 3.3 volts.

That did indeed appear to be the problem. Hard to tell what pin is the 5V by looking from atop.
