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 ...

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 ...
Communication example between arduino and RPi with JSON, avoiding the 32 byte limitation of I2C. RPi acts as master, arduino as slave, and the communication is made through several request: RPi asks for data length to arduino. Arduino answers with the JSON length. RPi gets the data in 32 ...
