Features

The project consists of 4 main files and should be executed on a computer.

• listports.js: Find the serial port the Arduino Uno communicates with your computer.
• mam_receive.js: Extract the stored data from the Tangle using MAM and display the data.
• sensor.js: The DHT11 sensor data (temperature and humidity) is read and displayed.
• mam_sensor.js: The DHT11 sensor data is read and published to the Tangle using MAM.

Installation

npm install

Usage
