When prototyping a project using an Arduino, there are a few things that are pretty much required equipment. A computer for generating sketches is typically one of those things, but [Adam] over at Teague Labs is looking to change all that with his current project, the Computerless Arduino.
Instead of using a computer to alter the code running on the Arduino, they have implemented a real-time code interpreter using a Teensy 2.0. The microcontroller is connected to a 5-button LCD display where the user can view the status of any port, view the current running code, as well as alter that code on the fly.
The real-time instruction set is somewhat limited, making it a breeze for newcomers to begin using the Arduino. While that may turn some people off, it still has enough functionality baked in to handle moderately sized projects as well.
