But there’s a new library available which seeks to reduce the latency of software-based serial communications so that you don’t have to worry about it.

The module can be used as a standalone module with attached battery, speaker and push buttons or used in combination with an Arduino or any other microcontroller with serial communication (UART) ...

UART is a versatile and widely used communication protocol that is suitable for a wide range of applications. Some of the features of UART include: 1.

In it, he shows an example of using all three ESP32 UARTs from an Arduino program. He calls the third port “secret” although that’s really a misnomer.

On-board jumpers allow the transmitter and receiver to be connected to a choice of Arduino I/O pins – default is Tx is connected to UART Serial pin 1 and Rx to UART Serial pin 0. The associated ...

“Additional hardware serial ports: No more bit banging!The need for a second UART port ( and one that is not shared with USB) on the Arduino Uno is so great that the “SoftwareSerial” library ...

UART communication can be used for a wide range of applications, and it is commonly found in microcontrollers, computers, and peripheral devices.

It then receives serial data from the communication channel and converts it back to parallel data that can be used by the computer. UART communication can be used for a wide range of applications.
