![]() Open the Arduino IDE and create a new sketch named FunctionGenerator with the code shown below. This section will describe how to generate and display waveforms using the Serial Plotter. ![]() ![]() If you need assistance with your particular setup, post a question in the comments section below and I, or someone else, can try to help you. I am using the Uno WiFi R2 in this tutorial to take advantage of the on-board inertial measurement unit (IMU) so that I do not have to connect additional hardware. If you are using a different Arduino board or computer setup, the vast majority of this tutorial should still apply, however, some minor changes may be necessary.

My development system consists of the Arduino Uno WiFi Rev2 development board connected to a macOS based computer running the desktop Arduino IDE. You know what they say about assumptions. I only realized recently that it is actually used for plotting values on a graph and can be a valuable tool for visualizing data along with debugging code. I had previously seen it in the Tools pulldown of the main menu, but had assumed that since I did not have a physical plotter, it did not apply to me.
