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?
IMPLEMENTATION
