Hands on exercises in introductory EET courses provide students with interesting instructional tools to pique their inquisitiveness and increase their knowledge. The application specific exercise being described was developed to provide students an experience connecting basic analog and digital circuits to produce a system for a specific application. While negotiating the path to the desired goal, students experience working with units of measure such as time, distance, velocity and associated

The exercise provides an opportunity for them to use light emitting diodes as a sender-receiver system in conjunction with basic circuits to measure the speed of an object passing between the sender-receivers. Additional information is obtained from the sensor system also allows the calculation of the object's width. This paper describes the physical structure of the exercise, the circuits developed, a description of their layout and implementation and the methodology involved in their design. Laboratory problem solving application and calculations based on this exercise are described, and laboratory scenarios are presented.
