Engineering at Dordt College

I’ve written a few times about what is happening in my EGR 204 Microprocessor and Digital Logic lab. (Previous blog entry is here.) At this time the students are working on a second design project. This project must demonstrate sequential behavior—actions that depend on something that happened previously. The students may choose from several given projects or propose their own project. A quite popular project is a traffic light controller. Students use push-buttons to emulate the sensors in the road which detect traffic. They use light-emitting diodes to emulate the traffic lights themselves. Then they design the digital logic which causes the lights to respond properly to traffic. Click the picture above and you can watch a Quick-Time movie of Andrew Friend and Phil Stam demonstrating their traffic light controller. (Andrew and Phil took this class in the spring of 2006. Thanks Andrew and Phil for providing this video!)
