In today's project, I am going to make a flip-flop circuit by using the most popular NPN transistor BC547 A Flip-Flop LED flashing circuit is a fundamental circuit that delivers a continuous square ...

In this short tutorial, we will show you how you can build yourself a transistor-driven color-changing RGB LED lights. The building process is simple and requires only a few transistors, capacitors ...

A previous Design Idea describes a circuit that uses an astable multivibrator to drive an LED (Reference 1). The circuit in Figure 1 uses a simpler alternative approach. The circuit uses a 2N3904 NPN ...

Researchers from the Smart Lighting Engineering Research Center at Rensselaer Polytechnic Institute have successfully integrated an LED and a power transistor on the same gallium nitride (GaN) chip.

Ever wondered how a solar-powered lamp powers an LED with just a single 1.2 V cell? A closer look reveals a clever single-transistor voltage converter circuit. Curious how a solar-powered lamp powers ...

An LED dimmer circuit adjusts the brightness of LED strips, serving both as an energy-saving tool and a method to create aesthetic lighting. Call bells, designed to draw attention, are commonly used ...

A novel integrated circuit for driving LED lighting has been proposed, designed and fabricated. Besides the typical parts of LED driver, an integral part was added at ...

[Eric Wasatonic] had a box of SWB2433 transistors that he had very little information about. In order to discover their properties, he fired up his curve tracer to compare these transistors with more ...

This project demonstrates how to build a simple latching power switch circuit using an NPN transistor and a pushbutton, powered by a 9V battery. When the pushbutton is pressed, the transistor ...
