LED CHASER USING TRANSISTORS

LED CHASER USING TRANSISTORS


In this venture im demonstrating how might you make an extremely super drove chaser with transistors a few capacitors, LEDs and resistors. Transistors are extremely convenient little parts that have numerous abilities in gadgets fields. In the circuit I have made 5 LEDs chaser in a ring shape.


Segments Required: 


Transistors BC 547 ( or some other NPN transistor)

220 ohm resistors ( resistors worth can be changed by want)

20k resistor

5 LEDs (any shading)

3 to 12 volts battery or force supply

47uf capacitors (16v)

copper wire for rings

Stage 1 


In this first step I have made a copper wire ring and sol 5 LEDs + focuses on it fit as a fiddle as appeared in the pic given underneath

Stage 2 


In this progression I bound 220 ohm resistors with – sides of LEDs. so in this progression LEDs + and – side has been connected as appeared in the given beneath pics,

Stage 3 


in this progression I have welded Emitters purposes of 5 transistors with 220 ohm resistors. I have utilized BC transistors you can utilize any NPN transistor as per graph. Stage 3 pic is given underneath.

Stage 4 


In the wake of joining Emitters of all transistors with 220 ohm resistors. In this progression I have fastened 20 kilo ohm resistor with base purpose of transistor and + ring. you can change the estimation of resistor to increment and decline the speed of flickering or pursuing. Increment the estimation of resistor will diminish the speed of flickering and reduction the estimation of resistor will diminish the speed of squinting.

Stage 5 


in this progression I have taken an other copper ring and patched all producers purposes of transistor with it for giving – supply to all transistors as appeared beneath the graph.

Stage 6 


In this progression I have fastened 5 capacitors esteemed 47uf 16v with base of first transistor and authority of second transistor and thusly last capacitor join with gatherer of first capacitor and hover finished as appeared in the given picture.

Presently the time has come to offer capacity to the circuit append + wire of battery or supply with inward ring and – purpose of battery to the external ring. Circuit will work superbly and viably .

Last advance with battery is given beneath
