View Resource Remote Controller Teaching Element

This activity, from the Technological Education Pathways Partnership (TEPP), leads students in a teardown of a remote control to examine transmission function and signal analysis in the device. Students examine the circuit board and transmitter components in a simple DVD player remote, led by directions in PowerPoint format and lab directions in multiple Word documents. The activity is intended...

View Resource Thermostat Teaching Element

This lesson, from the Technological Education Pathways Partnership (TEPP), uses two PowerPoint presentations to lead students through the components of a digital non-programmable thermostat and how they work. A lab guide in Word document form presents the needed materials and directions for students to work with thermostat components in class, including building circuits, testing heating control,...

View Resource Motion Sensing Light Teaching Element

These slides, from the Technological Education Pathways Partnership (TEPP), lead students in a teardown activity to examine the components of a motion sensing light device. Wiring is exposed to add a manual toggle switch and then measure voltage and current. This setup can the be used to compare the performance of incandescent, CFL, and LED light bulbs. The activity includes a set of PowerPoint...

View Resource Light Technology Teaching Element

This lesson, from the Technological Education Pathways Partnership (TEPP), compares some of the different light bulbs available to consumers. Light bulb types examined include incandescent, LED, and compact fluorescent lamp. Three PowerPoint presentations outline a test the output of incandescent light bulbs, and teardowns of CFL and LED light bulbs; a PDF outlining self oscillating lamp circuits...

View Resource LED and Transmitter Characteristics

In this video from the ICT Center, learn about fiber optic transmitters. Explore the components of a fiber optic transmitter, including a source, a modulator, an electrical driving circuit, and fiber coupling mechanics. Animations illustrate how the process of spontaneous emission converts electrical information to an optical signal in a light-emitting diode, or LED. In addition, learn about...
