Welcome to MegunoLink.
MegunoLink is a program to connect your Arduino to your computer. It uses visualizers to interpret messages your Arduino sends and send commands to your sketch. Once connected you can:
- Plot graphs in MegunoLink using data collected from sensors on your Arduino.
- Build a user interface with buttons, input controls and labels. The controls can send commands that your Arduino sketch can act on.
- Monitor all the serial data your Arduino is sending.
- Save the Arduino serial stream into a log file.
- Create separate channels for sending important messages from the Arduino that are separate from all the clutter from the serial stream with the Message Monitor Visualizer
Your Arduino can send data to MegunoLink using all sorts of connections. Use the Connection Manager visualizer to setup the ones you want to use:
- USB/RS232: the most common Arduino connection. This is the one that starts
- Ethernet: if your Arduino has an Ethernet connection, MegunoLink can talk to it via UDP.
- Wifi: MegunoLink can talk to the ESP8266 or ESP32 modules using UDP.
- XBee Series 2 Pro: using an XBee in API mode? We’ve got that covered.
- File: this one is really just for testing. MegunoLink can read serial data from a log file and replay it for you.
MegunoLink can talk to as many Arduino’s as you like. All at the same time. You can mix-and-match connection types or even connect to one Arduino using several methods (WiFi for data and Serial for debugging, for example). Set it all up with the Connection Manager.
A demo of MegunoLink Pro in action can be seen in the video below. You can download the example Arduino program used in this demo here.
