Digital Electronics Random Number Project

Jan 04, 2017



Students learn to identify electronic components like resistors, capacitors, flip-flops, logic gates, digital timers and LEDs. Students learn to solder these components into a fiberglass circuit board, to create an electronic “roll of a single die”.  After building this project, students spend several months learning everything necessary to design this build from scratch. Students complete several projects, each representing a different piece of this overall design.

Students learn the challenges of converting a design on paper to a functioning product. Proper component placement, orientation and high-quality solder joints are required to get the LEDs to blink and then stop on a random number.

In semester 2 of Digital Electronics, students are challenged to create different designs that require knowledge of these same components. Students use software to design and simulate projects like the “Now Serving” LED display at a Deli counter, digital billboards and vending machine logic to dispense the chosen snack or drink. After successful simulation, students build a prototype of their design.

These projects combine traditional engineering design principles with hands-on prototype building skills. Students are naturally engaged by the project builds and participate in an ongoing evaluation of design lessons to gain the knowledge to create new designs.
