Well, it's basically the only option for debugging an Arduino. But sometimes, it is not possible or practical to run a USB cable from the Arduino or any other microcontroller into your computer. So I made this UART-WiFi board, based on the ESP8266-01, which is dirt cheap these days.

May 15, 2014 · We need to set up the wireless module with Arduino and also with a computer. It is different with Bluetooth or WiFi, you do not need to establish a connection by searching or keying in the pairing key :). Arduino with 434MHz (100 meters) Wireless UART, please make the following connection.

Apr 22, 2019 · Wireless transfer data to an Arduino by way of 433MHz transmitter/receiver modules by using the RH_ASK library.

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.

In this Arduino tutorial we will learn how to use the HC-12 wireless serial communication module which is capable of making a long range wireless communication between multiple Arduino boards, with distances up to 1.8km.

May 12, 2020 · After learning how the UART works, let us now build a simple sketch demonstrating how to use UART communication using Arduino Uno. Our project is about controlling the built-in LED of an Arduino remotely via UART.

Feb 21, 2022 · The 433MHz HC-12 SI4463 Wireless Serial Port Module provides a wireless 4-pin TTL-level UART interface (Vcc, Gnd, Tx, Rx) with 100 channels spaced 400 kHz apart, eight transmit levels, eight supported baud rates, and three different working modes.

All Arduino boards feature one or more hardware UARTs that can communicate with peripheral devices, sensors, gateways, and other MCUs using just 2 wires – RX and TX. This article provides a comprehensive guide to utilizing the Arduino’s built-in UART hardware to add serial communication capabilities to projects.

Jul 26, 2018 · The OSOYOO UART LoRa wireless module targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, smartphone detection, building automation, and so on. In this tutorial,we will show how to use the uart LoRa module with the Arduino board.
