In this article, you will learn the basics of Universal Asynchronous Receiver-Transmitter (UART), a serial communication protocol that can be used to send data between an Arduino board and other devices.

Asynchronous Serial Communication With AT Commands: If you want to combine two Arduino boards where one collects sensors data and the other sends that data to a server like MQTT, here are some easy code lines that will allow you to do that.

Apr 23, 2025 · UART (Universal Asynchronous Receiver-Transmitter) is one of the most used device-to-device communication protocols. It allows an asynchronous serial communication in which the data format and transmission speed are configurable.

Jun 11, 2017 · This Serial Monitor can receive and display data/messages that will be sent from the Arduino; it can also take commands (in the form of ASCII characters) from the PC and send them to the Arduino using the virtual UART Port.

There are basically two types of serial communication: Asynchronous, where both ends have to (pretty precisely) agree on the speed of communication (baud rate), and synchronous, where one end tells the other end what the speed is by providing a discrete clock signal.

In this tutorial, we will perform UART or serial communication between two Arduino boards using UART software library of Arduino IDE. To debug and program Arduino using a USB port, the serial port which is known as Universal Asynchronous Receiver/Transmitter (UART) Communication is used.

UART (Universal Asynchronous Reception and Transmission) is a pretty simple protocol for serial communication that lets hosts communicate with different serial devices. UART supports serial, asynchronous, and bidirectional data transmission.

USART (Universal Serial Asynchronous Receiver Transmitter) is a serial communication protocol used to transmit/receive data serially at a specific baud rate. Several devices such as GPS, GSM, RFID, sensors, etc need to communicate with the microcontroller for …

Oct 26, 2021 · When you use the Arduino Uno, the usual way to communicate asynchronously is to use the Serial object, which is an instance of the class HardwareSerial. The hardware UART does most of the work and only when a byte has been received or a …

Arduino Wi-Fi Shield 101 is a powerful IoT shield with crypto-authentication, developed with ATMEL, that wirelessly connects Arduino to the Internet using the IEEE 802.11 wireless specifications. It is based on the Atmel SmartConnect-WINC1500 module, compliant with the IEEE 802.11 b/g/n standard.
