Simple Led Flasher Using Bc 547 Transistor How To Make

Simple Led Flasher Using Bc 547 Transistor How To Make Led Blinking Welcome to aslam hossain's channel!simplest led blink circuit by aslam hossain.in this tutorial video, we will guide you through building the simples. This led flasher uses a transistor bc547, a 4700uf capacitor and a 1k ohm resistor the blinking time can be adjusted by increasing or decreasing the value.

Diy Led Blinking Flasher With Bc547 Transistor Easyproject4u Youtube The components using in this led blinking circuit is a single led, bc 547 npn transistor and a 1000uf 63b electrolytic capacitor. the circuit will not works on 3v or 9v battery it needs at least 12v dc to start the light to blink. the proper connection circuit diagram and connection video is also attached with this article. Here is how to make a simple led flasher circuit using single transistor , for led flasher circuit the components are : t1 = bc 547,r1 = 1k,c1 = 470 uf 16. A flip flop led flashing circuit is a fundamental circuit that delivers a continuous square wave flashing output. this circuit is commonly utilized for alarming and indicative purposes like in tig welders etc. in this project, we are utilizing two transistors of bc547. the bc547 transistor is an npn transistor. Parts list for the proposed single transistor led flasher circuit. r1 = 2k7, r2 = 100 ohms, t1 = bc 547, c1 = 100 uf to 470 uf. led = any type, any color. the flashing rate could be varied either by changing the value of r1 or c1 or both together. but the supply voltage not be less than 9v otherwise the circuit might fail to work correctly.

Construction & working. this led flasher circuit or blinking circuit constructed by two cross coupled transistors, it can be either npn or pnp, here we have used two bc547 transistors. if you want to produce high frequency output then use high switching speed transistor in this circuit. here both bc547 transistors are biased as common emitter. The above circuit uses a combination of bc 557 and bc 547 transistors in such a way that bc 547 npn transistor conducts for a very brief time making the led light. the combination of resistors and capacitors determines the timing of the flasher, and the time duration is proportional to ‘r x c’. capacitors charges through the resistors.
