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

Embrio is a different kind of visual programming environment which doesn’t try to mimic traditional programming, instead you create your program out of multiple “agents” which each have one job and all run at the same time in parallel. Agents attach to each other, activating and suppressing other agents similar to neurons in a brain. Agents are implemented by adding and connecting visual nodes, and you can write your own custom nodes giving you the full power of traditional coding wrapped in an easy to use graphical interface. Work with a live connection to your Arduino to get real time feedback and interaction, avoiding the cumbersome compile, upload, and test loop of traditional programming.

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!

See the list of compatible boards.

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.

Version 2.2.3.2

Bugs Fixed
Arrays in the declaration section of a node weren’t compiling correctly on Arduino.
Errors on nodes weren’t clearing.
Integer outputs on nodes that use the Min or Max values had a compile issue.

Version 2.2.3.1

Bugs Fixed
Fixed a bug where reusable node groups were using an input's default value when the exposed input had no value.
Cleaned up the agent processing timing code to avoid what could have been causing an agent to stop processing.

Pololu Maestro Servo Controllers

This node lets you control a bunch of servos with the Pololu Maestro family of servo control boards using the maestro-arduino library. A servo control board is great because it moves all of the hardware and software resources needed to control servo motors off of the Arduino and only takes up 2 pins to control a large number of servos. The board creates the smooth PWM signals needed to run the servos. You can also use these boards to control anything that's controlled by a PWM signal like LEDs.

Servo Control with UI

This tutorial shows how to control a Servo with an Arduino via a user interface running on a PC, connected by a serial cable. The project contains two controllers, one to run on the Arduino, and one to run on the PC with a UI made with HTML, CSS, and jQuery. The two controllers communicate with built in serial communication nodes.
