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...
A standard Arduino has a single hardware serial port, but serial communication is also possible using software libraries to emulate additional ports (communication channels) to provide connectivity to more than one device. Software serial requires a lot of help from the Arduino controller to send and...
The objective of this esp32 tutorial is to explain how to get started with the BluetoothSerial ESP32 library, in order to send data to a emulated Serial connection, operating over Bluetooth classic. The tests of this ESP32 tutorial were performed using a DFRobot’sESP-WROOM-32device integrate...
/*Multiple Serial testReceives from the main serial port, sends to the others.Receives fromserial port1, sends to the main serial (Serial 0).This example works only with boards with more than one serial like Arduino Mega, Due, Zero etc.The circuit:- any serial device attached to Serial p...

Basically you have to communicate using the Firmata protocol over Serial communication. That can sounds quite difficult to do at first, but don’t worry, there are also client libraries available for you that will handle all the communication out of the box!
