Switching Regulator are small circuit and easy to understand, as they take little energy pieces from input and send it to output step by step; then they turn power transistor ON and OFF fast and this controls voltage good. Also, they are different from linear regulators as it do not waste energy as heat. In […]

Relay Collector vs Emitter Connection: Which Is Better?
Relays are very important in electric circuit for switching ON/OFF, as they control big power load using small signal which is very useful. Also, engineers often use transistors to control relays for better switching and lower power loss, they can connect the relay coil to either the collector side or the emitter side of the […]
Different Types of LEDs: A Comprehensive Guide
LEDs are small light sources that consume less power and produce high brightness. Different types of LEDs, such as standard LEDs, high-power LEDs, RGB LEDs, and SMD LEDs, serve various applications, including TVs, flashlights, displays and decorative lighting. Therefore, today LED is everywhere and is very important part in human life. Working Principle of LEDs: […]
Seven Segment Display Circuit: Datasheet, Pinouts And Working
A Seven Segment Display is a simple electronic display device that shows numbers from 0 to 9. Moreover, it contains seven LED segments arranged in the shape of the number “8,” and engineers name each segment from a to g. By turning ON different segments, it can display different numbers. LEDs make the display bright […]
Understanding Photosensitive Devices Circuits
Light is present all around us and photosensitive devices can feel this light, as these are very useful electronic components which change their action when light falls on them. We use these devices in automatic lights, alarms and many other electronic circuits. In this article, for Understanding Photosensitive Devices Circuits we will learn about their […]
Hysteresis in Schmitt Trigger Circuit using IC 555
Schmitt Trigger is special type of comparator, which gives stable switching even if input signal is noisy or slow. We can use a 555 timer IC as a Schmitt trigger and it is also used in many projects. Furthermore, a Schmitt trigger provides two types of output: normal (non-inverting) and inverted square waves. Next, we […]
