And how serial communication works at the low level. If you want to learn more about UART Serial Communication Protocol. To initialize (start) the serial port, you need to call the Serial.begin() function and pass the desired baud rate value to it. Which is the rate at which we’ll be sending/receiving serial data.

The Arduino built-in library for the serial port doesn’t require you to enter any configuration parameter for the UART peripheral other than the Baud Rate. ESP32 Serial Port Initializationįirst of all, you need to initialize the UART serial port before you’re able to use it for sending/receiving any data. We can actually send numeric variables from the ESP32 to the PC and get the value plotted in a graphical interface inside Arduino IDE itself. And maybe check some flags, logic decisions, etc.Īnother use that we’ll also try in this tutorial is the serial plotting feature in the Arduino IDE. This is a very easy and quick way to debug your Arduino Applications by printing out the current variables’ values to the terminal screen and keep track of what’s going on. This is what we’re going to use in this tutorial to send data from the ESP32 to our PC over the UART serial port. One of which is hard-wired to the USB-TTL converter on the ESP32 dev board itself. Get The ESP32 Full Course Kit (List of components)Īs we’ve stated earlier in the introductory tutorial, the ESP32 has 3 UART peripherals.Or just refer to the table for the exact components to be used in practical LABs for only this specific tutorial. You can either get the complete course kit for this series of tutorials using the link down below. Arduino IDE For ESP32 (Setup Guide) Hardware Components.

Requirements For This Tutorial Prior Knowledge And finally, use the ESP32 to send some numeric data over the serial port and plot the data points in Arduino IDE serial plotter.

Then, we’ll discuss how to print numeric variables for debugging Arduino code. In this tutorial, you’ll learn how to use the ESP32 serial print function in Arduino IDE to print our first Hello world example.
