As our world economy and culture becomes ever more dependent upon electronic technology, there will be an ever increasing number of opportunities for students to enter electronic related careers. The purpose of the Electronics and Advanced Electronics courses is to give students insight into these opportunities. Students do not need to have any prior knowledge of electronics before entering this course. As students build many exciting projects, they learn a number of the introductory elements of electrical theory. The following are several of the projects that students build through the Electronics & Advanced Electronic courses:
1. Clap on/ Clap off circuit
2. Burglar alarm
3. Light detector circuit (similar to the lamp-posts in many people’s lawns that automatically come on at night.)
4. Infrared detector alarm
5. Door intercom system
6. Rail-road lights
7. Stop light
Electronics Class Projects
Video: Autonomous Car Projects
These are videos of the Autonomous Cars that Electronics classes built. The goal of this car is to be able to navigate out of a corner without human intervention. For this project, students placed a switch on the front of the car to detect when it hits a wall. When the switch is pressed, a signal is sent to the 555 timer IC chip which in turn sends a signal for a couple of seconds to a motor controller. This motor controller that Ryan built is a H bridge made from relays. This is designed to continually run the motor forward until a signal is sensed from the 555 timer IC. When a signal is sensed, the motor is then reversed for a couple of seconds. Great work!
Video: Burglar Alarm
Video: Clap-On, Clap-Off Circuit
This is a fun project that Electronics classes build that serves as a clap-on, clap-off circuit. In this project, students learn about three major integrated circuit chips including the operational amplifier, the 555 timer, and the flip flop. Students are also given the opportunity to learn about troubleshooting tools such as the oscilloscope through this project. Students are reminded that they do not have to have any knowledge of electronics before taking this course.

Video: Infrared Detector 1
Video: Infrared Detector 2
Video: Light Detector Circuit
This is a light detector circuit that the electronics class builds that is similar the lamp posts in many people’s lawns. This circuit senses when it is dark outside and tells a light to turn on.
Video: Light Sensing Car
The light sensing car is a fun project that the Advanced Electronics class will likely be able to accomplish this coming year. This project takes a computer mouse and its internal components to make a car that not only follows either light or darkness, but also reverses if it hits a wall. In this project students will learn about fundamental electronic components such as the op amp, light detectors, relays, and motor drivers. The following video shows one of these cars in action. This car is shown following the darkness on the outside of an area lit up by a halogen light that is moved around the room.
Video: Rail Road Light Control Circuit
The following video is a fun circuit that the Electronics class built that serves as an example control circuit for a set of rail road lights. To make this circuit, the class learned about an integrated circuit chip called a 555 timer. They first used the 555 IC to build a basic control circuit that made one LED flash on and off. The students then connected this control circuit to a relay which switched between two 120V powered light bulbs. Great work class!
