Topic: Chapter 5 - Issues with potentiometer (Read 3853 times) previous topic - next topic


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.
You will save everyone's time if you read and follow the forum guidelines.  https://forum.arduino.cc/index.php/topic,148850.0.html


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