The Propeller Experiment Controller

This page provides resources related to the Propeller Experiment Controller. I offer is free, open-source software that enables any Parallax Propeller microcontroller to excel in the role of an experiment controller.

The purpose of the Propeller Experiment Controller is to make any form of computer-controlled automation and data recording easy and affordable. The software is free, and the Propeller microcontroller costs less than $100. The Propeller Experiment Controller was designed to primarily to conduct automated research experiments on learning and behavior in humans and animals. However, it is also useful in a wider variety of situations, including automated training devices, automated enrichment devices and classroom demonstrations.
