Visual, real-time, agent based programming for Arduino. Now available for Windows, Mac, and Linux.

A visual, real time programming envrionment for the Arduino!

Agent Based Programming

An agent is a little piece of a program that has one job. Agents connect to and turn on and off other agents. An Embrio program is made up of multiple agents running in parallel.

Real Time Connection

Work with a live connection to your Arduino, see how your program works as you build it!

Compiles To Arduino

When your program is done, it can be compiled to run entirely on your Arduino! The profiler tool gives you accurate resource usage information while you work.

Learn more by going through the growing library of video tutorials, for example:


Button Toggle - This tutorial shows how to set up a button in Embrio. It reads a digital input value from a push button, and passes that value through an Above or Below node to get a trigger event from it to toggle a switch. Finally it uses a timer node to limit h...


Color Fading RGB LEDs - This project shows how to randomly fade the colors of RGB LEDs, as well as control their speed and brightness with potentiometers. The project also demonstrates how to encapsulate groups of nodes as Functions which can be reused multiple times.


Autonomous Car - In this 3 part project we’ll see how to program an autonomous robot car using Embrio. The car has 3 behaviors. It wanders around, avoiding obstacles by turning away from near by walls and stopping before hitting a wall. Every so often it stops and...
