Hi every one today I'm going to give you a Wonderful LED circuit diagram.This circuit is called Multivibrator circuit diagram.Here two LEDs are blinking one by one.Here I have used common IC CD4069. Note # Build this circuit on a P.C.B # Don't supply more than 15 V #Use two color LEDs

Today I'm going to give you a wonderful circuit diagram.Most of you ask about police car light systems.So I thought to give you a police car light system circuit diagram.Here I have used two ICs one is IN4017 and the other one is  40106.Here I have used only blue colour LEDs If you like to add any other colour you can add them.I think after adding this circuit for your car you can attract others.      Note  # Build this circuit on a P.C.B # Don't use more than 6V

T he most widely used products in the Electronics industries is a transistor and its also the major component of any electronics equipment, so its necessary for all of us to know what basically a transistor is....and what can be its basic applications in daily life ? When any lecturer asks you in VIVA or as a general question "What is a transistor? And its application…." The basic answer for this is  A transistor is "Transfer of Resistance" and if it is to be technically explained then its as below.... A   transistor   is a   semiconductor device   used to   amplify   and   switch   electronic   signals and electrical power.   Prior to the development of transistors,   vacuum (electron) tubes   (or in the UK "thermionic valves" or just "valves") were the main active components in electronic equipment. ADVANTAGES : The key advantages that have allowed transistors to replace their vacuum tube predecessors in most applications are   Small size

In many situations, we need to use MOSFETs configured as high-side switches. Many a times we need to use MOSFETs configured as high-side and low-side switches. Such as in bridge circuits. In half-bridge circuits, we have 1 high-side MOSFET and 1 low-side MOSFET. In full-bridge circuits we have 2 high-side MOSFETs and 2 low-side MOSFETs. In such situations, there is a need to use high-side drive circuitry alongside low-side drive circuitry. The most common way of driving MOSFETs in such cases is to use high-low side MOSFET drivers. Undoubtedly, the most popular such driver chip is the IR2110. And in this article/tutorial, I will talk about the IR2110. You can download the IR2110 datasheet from the IR website. Here's the download link: www.irf.com/product-info/datasheets/data/ir2110.pdf First let’s take a look at the block diagram and the pin assignments and pin definitions (also called lead assignments and lead definitions): Fig. 1 - IR2110 block diagram (click on image to enlarge)

PWM is used in all sorts of power control and converter circuits. Some common examples include motor control, DC-DC converters, DC-AC inverters and lamp dimmers. There are numerous PWM controllers available that make the use and application of PWM quite easy. One of the most popular of such controllers is the versatile and ubiquitous SG3525 produced by multiple manufacturers – ST Microelectronics, Fairchild Semiconductors, On Semiconductors, to name a few. SG3525 is used extensively in DC-DC converters, DC-AC inverters, home UPS systems, solar inverters, power supplies, battery chargers and numerous other applications. With proper understanding, you can soon start using SG3525 yourself in such applications or any other application really that demands PWM control. Before going on to the description and application, let’s first take a look at the block diagram and the pin layout. Pins 1 (Inverting Input) and 2 (Non Inverting Input) are the inputs to the on-board error amplifier. If you a
