INTRODUCTION

This pulse generator can also be called oscillator. They are sequential logic circuit which can be either synchronous or asynchronous circuit.

They have application in our smart electronic gadgets like: Digital measuring tools, Microwaves, Digital alarm clocks, Counters, Security systmes , Alarm Clock , Elevators, Smart radio etc.

COMPONENTS LIST

Componets used Description

Resistor ( R1) To reduce the amount of current flow, so that the current flows doesn't damage the other devices connected.

Resistor ( R2)

Resistor ( R3)

Resistor ( R4)

555 Timer It produces oscillation.

Electrolytic Capacitor It store charges and dissipates it when needed.

Polyester Capacitor It store charges and dissipates it when needed.

Batteries It provides direct current.

Leds It provides illuminations.

Project Boards It provides interconnections

Multimeters Used for measurements

SCHEMATIC DIAGRAM

DESIGN DEVELOPMENT

The design developmental flow chart is given below

start

what to be achieved, list of all components needed

Does the all the inputs parameters i.e.

(what to be achieved, components list)

meets design specification

Perform all interconnection, Calculate the duty circle to

check design meet specification.Needed for formular

freq=1/t= 1.44 / ((r1+r2*2)*c) duty cycle= (r1+r2)/(r1+2*r2)

End

Does Everything works perfectly?
