3. 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.

4. 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

6. 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?
