First, we initialize the Serial communication, and choose a baud rate, here 9600. 9600 is a commonly used baud rate, and also a pretty low one. In your future applications you can use a baud rate of 57600 or even 115200 without any problem. For this tutorial we’ll continue with 9600...
Arduino Serial Monitor screen Your sketch must call the Serial.begin() function before it can use serial input or output. The function takes a single parameter: the desired communication speed. You must use the same speed for the sending side and the receiving side, or you will see ...

In this tutorial, we will learn how to perform RS485 serial communication between two Arduino boards using 5V MAX485 TTL to RS485 module.RS485communication is used in industrial Modbus to communicate with various devices. We will follow the RS485 serial communication protocol and demonstrate it wi...

In this tutorial we will check how to detect the client disconnection event when using the Bluetooth Serial library of the Arduino core, running on the ESP32. The tests were performed using a DFRobot’s ESP32 module integrated in a ESP32 development boar
Serial Communication: A Way To See What Your Arduino Is DoingArduino has an incredibly simple and convenient serial communication library that enables you to transmit data over serial with only two lines of code! The Arduino serial library will be useful throughout these tutorials as it provides ...
