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

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.

Print to LCD - This project uses a custom Arduino node and some Text Activator nodes to print text to an LCD. It cycles through 3 messages with the push of a button.


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...

Bezier Curve Node

The bezier curve node lets you convert a linear input to a curved output. It is especially useful for working with physical devices that have a non linear response, or adding ease in and out throughout a project for a more natural look.

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.

Activation hides decimals

EmbrioAdmin: Thanks, good to know what the issue is. Strange that you get decimals some times and not others, I would think it would be broken or not. I'll investigate and have a fix updated soon.

Custom Nodes Overall

EmbrioAdmin: You should be able to access _value the way you posted, I suspect the problem is that you wrote Input_In_Min instead of Input_In.Min. Does it work if you change it? Further evidence that I need bett

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.
