Due to the advantages like low voltages, long life, cheap, reliable, fast on-off switching etc, the LED’s are used in many applications. The various applications of LED are, All kinds of visual ...

In this post, two LED blinking circuits are given below. First one is dancing bi-color LEDs (two different color LEDs) where the two color LED will run in sequence. In the second circuit, we will ...

In this article, we will make a buck converter using 555 timer IC and a IRFZ44N N channel MOSFET and use it as LED dimmer circuit or as a motor speed controller circuit. This circuit is basically a ...

A transistor tester can be a handy addition to your electronics workbench. This versatile transistor tester design, first presented a decade ago, enables you to quickly assess the functionality of NPN ...

I know very little about electronics, but if you give me a schematic and a pile of parts, I can more-or-less assemble them correctly.<br><br>I am trying to build a simple circuit to simulate the ...

An adaptable classroom activity designed to introduce students aged 8-14 to e-textiles and basic circuitry. The activities can be used as standalone sessions to introduce students to the basic ...
