As the final project in this course, students created an LED display-matrix. The visual activity of the display was driven by varying conditions of light reported by sensors mounted on the outside of the building.

Students built two mechanical switcher assemblies from salvaged parts: pieces of scrap wood, PVC pipe, and motors salvaged from CD drives. Visual activity on the final display was changed by controlling the speed of these two motors by varying the current applied.

Here, students are connecting the teleo board to the light sensors and the LED display matrix.

Everything is powered up and working. The total project, from concept to completion, took about 3 weeks…
