An Arduino Uno 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 ...
This library is great, helps me sending JSON data from Arduino to Web. But I also want to send JSON data from web to Arduino to control some of devices. At the moment I'm using serial interface for communication between Arduino and Node.js script. I managed to send JSON stream to ...
arrays, or a combination of both. An object in JSON is enclosed in curly braces { }. Inside the object, data is represented as a collection of key/value pairs. A key/value pair consists of a field

Arduino library for LoRa communication with Semtech SX126x chips. It is based on Semtech's SX126x libraries and adapted to the Arduino framework for ESP32, ESP8266, nRF52832 and RP2040. It will not work with other uC's like AVR. ...
