The program contains easy-to-use tools to record data received from serial devices, and to plot numerical data on up to 4 separate graphs in real-time. ![]() This program is designed as a replacement for the serial monitor contained within the Arduino IDE. ![]() This project is a Processing-based serial terminal and graphing program for the analysis and recording of data from serial devices, such as Arduinos. Here is the full code listing for this example.Serial Monitor and Real-time Graphing Program And we’ll plot it graphically on the Arduino IDE’s Serial Plotter Tool. I’ll create a variable and assign to it sinusoidal waveform data points and send them one by one over the serial port. Here is an example to demonstrate the functionality of this tool. You have to arrange the data to be plotted on your own and send them in a specific order as we’ll see in the examples hereafter in this tutorial. The Arduino serial plotter tools displays color legends by default if you’re plotting multiple variables at the same time and it has no labeling for each plot curve. ![]() ',' per line as we’ll see in the second come example hereafter in this tutorial. You just need to send comma-separated values The Arduino Serial Plotter tool can also display multiple plots on the same graph grid. Unless you’d like to plot two quantities together and pre-scaling needs to be done in software. No need to do software scaling for your variables in code because the Arduino’s serial plotter will do it on its own. The Arduino Serial Plotter has an auto-scaling feature which means you don’t need to worry about the scale for the Y-Axis (value). Showing a graphical plot for different values & flags can be extremely helpful. Especially things that show weird timing behavior or if you’re trying to catch some runtime bugs. Which can be really helpful for debugging or monitoring the behavior of your code. It enables you to plot variables sent over the serial communication port and have a graphical visualization of the variable’s value over time. The Arduino serial plotter is another handy tool that’s also built into the Arduino IDE. In a previous guide, we’ve discussed the Arduino Serial Monitor tool that’s already built in the IDE itself.
