Discover the step-by-step process of creating a powerful music reactive LED strip circuit in this comprehensive tutorial.

This is a very simple but useful project, strobe navigation lights for rc airplanes, or you can adjust the flashing time and ...

The “two flashing led” circuit is designed for 9 Volts but it works at lower voltages too. In this design we used red leds but by changing the series resistors R1 and R4 you can also use different LED ...

2) LED as a Continuity tester: The above shown circuit is LED as continuity tester. This circuit is used for checking continuity of cables, connectors and switches. When A and B terminals are shorted, ...

Midwest Circuits' LED street-light technology shines Published: Jun. 12, 2008, 9:00 a.m. By Sarah A. Rigg Patel ...

Or voltage variation can occur if an LED in one string is shorted. In Fig. 2, the power-limit circuit is formed by R11, R12, R13, R14, Q11 and Q12.

Business Woman-led circuits maker going strong By Dan Voorhis December 23, 2012 12:20 AM ...

Circuit diagrams like the one below are used to illustrate a circuit’s different components, or parts, and the direction of its current: A switch in a circuit is any component that can open or close ...

Many equipment manufacturers prefer protection circuits combining resettable overcurrent protection devices with upstream fail-safe protection. In this example, R1 represents a ballast resistor used ...

In the simplest circuit, you could drive an LED with a TL431. Connect an LED and a current-limiting resistor up to the cathode and ground the anode of the TL431.
