Arudino Serial MonitorĪccess the Arduino Serial Monitor using Tools -> Serial Monitor. If the Arduino sketch is working correctly, a running list of numbers is shown in the Arduino Serial Monitor. When the potentiometer is dialed back and forth, the numbers streaming down the Serial Monitor should change.

The output in the Serial Monitor should be a running list of numbers between. If a running list of numbers can't be seen in the Arduino Serial Monitor, ensure, and are selected.

Also, make sure the Port is set correctly in the Arduino IDE under Tools -> Port. To access the Arduino Serial Plotter, select Tools -> Serial Monitor in the Arduino IDE. Note the Arduino Serial Monitor needs to be closed before the Arduino Serial Plotter can be opened. If the sketch is working correctly, potentiometer rotation produces a moving line on the Arduino Serial Plotter. The output of the Arduino Serial Plotter should be a running line graph.
