A highly sensitive sound activated LED lamp circuit can be built using just a few transistors and resistors. The circuit is actually a high gain MIC amplifier circuit which amplifies the external sound hitting the MIC. The amplified signal is then used to momentarily illuminate a bunch of LEDs. What does the Circuit do? Basically, […]

This IC is widely used for applications which demand high efficiency and a compact form factor, for example operating portable devices, IoT modules, and other low-power electronics. Here’s the complete datasheet for the MP1584: Electrical Characteristics Pin Configuration […]
IC 4027 Datasheet, Pinout Working, Application
The CD4027 is a dual J-K flip-flop IC with reset that can be used in a variety of digital logic applications. It has two independent flip-flops, each with a J and K input, a clock input, a reset input, and complementary Q and Q-bar outputs. The CD4027 operates on a wide range of supply voltages […]
Design your own Sine Wave Inverter Circuit from the Scratch [Tutorial]
In this article I have explained comprehensively regarding how to design a sine wave inverter without any form of coding or complex circuit designs. The included designs are simple yet extremely precise with their sine waveform structure. You might have often felt discouraged, thinking that making a sine wave inverter from the scratch can be […]
How to Connect Resistors in Series and Parallel
There are three ways to interconnect resistors: series, parallel and in combination of series/parallel. When resistors are joined in series, the current passing via one resistor also passes through the next. When resistors are joined in parallel, they are wired across each other, resulting in the same voltage across each resistor. When resistors are connected […]
High Efficiency Solar Charger Circuits using Switching Regulators
Solar power or electricity from sun light is so abundant that we can afford to waste it or dissipate it in the form heat. This means that we can use large, high power solar panels to charge batteries with lower power without bothering about how much solar energy is being wasted and how much the […]
