Modern automotive matrix lighting often utilizes strings and matrices of LEDs, requiring an increasing number of integrated circuits to control them. New designs must usually pack more electronics in ...

New advances in transistor technology could make the light-emitting diode (LED) the commercial light source of the future. Although known for long life and low energy consumption, the LED uses a DC ...

LEDs are durable and save energy. Now researchers have found a way to make LED lamps even more compact while supplying more light than commercially available models. The key to success: transistors ...

The transistor is one of the most important components in electronics. By switching or amplifying electrical signals, transistors make sure that our smartphones, computers and even coffee machines do ...

Let’s say you want to blink an LED. You might grab an Arduino and run the Blink sketch, or you might lace up a few components to a 555. But you needn’t go so fancy! [The Design Graveyard] explains how ...

You can use an LED as a photoelectricsensor. A previousDesign Idea shows that such a switchis highly power-efficient, consumingalmost no power (Reference 1).However, you cannot adjust that ...

Transistors, the tiny switches that flip on and off inside computer chips, have long been the domain of electricity. But scientists are beginning to develop chip components that run on light. Last ...

The polarity markings on LEDs (Light Emitting Diodes) seem to be a common cause of confusion. The polarity may be indicated by a flat section on one side of the body or by one lead being shorter than ...
