555

Astable

Multivibrator.PRJPCB

Classical

555

timer

circuit

This

is

the

obligatory

555

SPICE

simulation,

configured

in

astable

(oscillator)

mode.

Adjusting

for

Astable

operation

component

values

around

the

circuit

will

reveal

how

the

duty

cycle

and

frequency

of

the

555

based

oscillator

can

be

manipulated.

555

Monostable

Multivibrator.PRJPCB

Classical

555

timer

circuit

This

is

the

obligatory

555

SPICE

simulation,

configured

in

monostable

(one‐shot)

mode.

The

for

Monostable

operation

timer

is

triggered

by

a

SPICE

pulse

source,

and

adjusting

the

component

values

R1

and

C1

will

show

how

pulse

time

can

be

adjusted.
