Question Statement:
In this assignment, students are provided with the design Car Indicator Light Circuit using basic 555 timer IC. We have designed this circuitry using “Electronic Work Bench” (which can be download from VU-LMS download section).

Car Indicator light working mechanism:
When the indicator is triggered, the indicator light will blink for a pre-defined N seconds.

We have used 555 timers in two different states.
• Mono-Stable State
• A-Stable State

Using Mono-Stable 555 timer, after triggering the switch (using Space bar in Electronic Work Bench) will generate 20 seconds UP clock signal.

A-Stable 555 timer is set to generate a clock with duty cycle of 50% of 2 secs (1 sec Clock UP time and 1 sec Clock DOWN time) and will be controlled through Mono-Stable 555 timer output.

By cascading these two 555 timers (Mono-Stable and A-Stable) the output LEDwill blink for 20 seconds (1 sec ON and 1 Sec OFF).

You are required to go through the 555 Data Sheet and Assignment # 04 Electronics Work Bench File (using Electronic Work Bench) and calculate the values for resistors R1, R2 & R3 to generate the specified timing cycles.

555 Mono-Stable Timer
C1 50µF
R1

555 A-Stable Timer
C2 50µF
R2
R3

Note: R1, R2 and R3 are required where we are using capacitors C1 and C2 of 50µF in diagram given above.

Required supporting material:
Electronics Work Bench
555 Data Sheet
Assignment # 04 Electronics Work Bench File

aoa

marha which formula did u use for calculating R2 and R3???

plzzz reply.i m waiting

R2 n R3 k liye konsa formula use kiya??

HERE IT IS R1 = 363.636
R2 = 10
R3 = 10

send a corect file plz  dears 

i will be thankful to u

here

R2 and R3 kesy find kin?? r ye sba kis unit mian karni hian?? plz bata den jaldi se

kohms

Y R1 = 363.636kasay aya hai as ko electoric work banch me kasay karay gya

http://www.ohmslawcalculator.com/555-monostable-calculator ISS WEB SITE MA JAOO AUR CAP KE VALUE DALO AUR 20 SEC LAKIH VALUE A JAYE GE 

complete  and accurate solution send kr den fellows . 

very very very easy assignmentt

http://www.ohmslawcalculator.com/555-monostable-calculator mgo to this site enter the capicator value 50 and timeperiod 20sec u will find r1 value and then same a stable value ko b asi tarah find kar loo and then ecetronic work bench softwae download kar k
