A model boom-gate using an Arduino, servo-motor and a reed-switch. (Oh, yeah... and a little plastic truck!)
The project I am on at work at the moment is a large Physical Access Control System (PACS). We have automated some of the testing of physical devices with an I/O interface and API into the control system.
As a bit of fun I built this to hang of the controller rather than watching events and status updates at a computer console.
The code / state machine, very accurately, simulates the behaviour programmed into the PLCs of the actual boom-gates that are controlling access on several mine-sites and ports all across Queensland.
The implementation of this project is very simple. (Though the application is a little novel, I think.)
I have blogged about the build and code design here
