5LEDs Chaser Using Transistors

5 LED chaser with transistors

This simple 5-channel LED chaser using transistors can be used in any application requiring LED light effects. This circuit is build by using npn transistors, capacitors and resistors. 5 LEDs are blinking as shown in this video gif . you can connect more LEDs as this sequence by adding some more transistors.   Step By […]

Flip Flop using timer IC 555

flop flop with timer ic 555

In this project i am going to show A very useful and beautiful flip flop circuit using timer ic 555. The circuit is able to blink 8 super bright blue and Reds LED’s. The circuit is build around a famous 555 timer IC which is wired as an a-stable multi vibrator here. The LED’s are […]

Flip Flop circuit using Transistors

Flop Flop Using Transistor

This D Flip Flop circuit using Transistors is a classic commonly used flip flop circuit. This flasher circuit is very popular and it is usually the first circuit for building when starting electronic circuit. The circuit diagram is given below. In this project we examine one of the most valuable circuits  the flip flop. Originally it […]

Door Bell With 555 Timer IC

Doorbell is a very common and useful electronic device used in houses,offices and etc. Among electronics students and hobbyists, doorbell circuit project is very popular. So in this tutorial i am  going to build a doorbell with 555 (timer) IC. The main feature of this doorbell is that we can control the time duration for which it keeps […]

How To Use Transistor As A Switch

transistor as a Switch

Use Transistor As A Switch In this artical we have explained the Use Transistor As A Switch in different applications.  A transistor is a three-terminal semiconductor device which can be used for switching applications, amplification of weak signals and quantities of thousands and millions of transistors are interconnected and embedded into a tiny integrated circuit/chip. A […]
