A visual, real-time development tool for Arduino programming.

A visual, real time programming envrionment for the Arduino!

A New Development Strategy

Write low level Arduino code to interact with hardware, then structure your program and logic in a powerful yet easy to use, highly parallel “agent based” architecture.

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.

Check out this short video for more information, then download and try it out for yourself!

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


Fade LED - This tutorial shows you how to use an Output node and a repeating Timer node with an end behavior of "return" to make an LED fade on and off.


Rotary Encoder With Interrupts - This tutorial uses a pre-built node group to encapsulate a 5 pin rotary encoder. A custom Arduino node wires up 2 interrupt routines to count ticks. The amount of ticks per rotation can be set, and roll over can be turned on and off at run time. ...


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...
