For anyone that this circuit didn't work, try the following: instead of doing 1:00 from pin 4 to rail, try placing 4 to 8 on the same timer. I did this and the circuit suddenly started working.
I am offering you my daughter in marriage. You just saved my academic career. Like seriously, you don’t even have to pay the dowry. I love you so much.
For everyone whose lights are not operating properly, the circuit diagram has a problem. The resistor should be connected with the pin 3 of second IC and then the anode of green led. That is the mistake in the circuit. In the circuit diagram, resistor is connected to the ground at the end, which is wrong. Also I used 470 ohm with red led, 220 ohm with yellow led and again 220 ohm with green led.I hope it helps, best of luck.
Thank you for showing this. I have looked for, and seen dozens of traffic lights, but they don't change lights in the right order or timing. I kept thinking, It has to be possible without software. You did it. Thank you.
Here in the UK when going from red to green you have red and yellow together when going from red to green (Red > Red & Yellow together > Green). The other variant is if it's a pedestrian crossing, where it might be (Red > Flashing Yellow > Green)
Bro I connected the circuit (copied every instruction) 8th time still I'm not getting the proper output, my led is not glowing, can u pls help me with this .
Excuse me, what causes the first lamp to turn on, the second to turn off, the third to turn off, the second to turn on, and the first to turn off, and the third to turn off?
A modified version of this would be really cool in a miniature build or something. My art hobby and electric engineering hobby parts of my brain are becoming friends and it's scary.
I made the circuit but the yellow stays on, that is, the green lights up, then the yellow lights up and when the red lights up, the yellow stays on, why? Thanks and congratulations for the video
Traffic lights dont use yellow before going to green. They only use yellow when going from green to red. At least in the united states… though there may be some state that uses the yellow light to transition to red or green i just don’t know about.
Please be careful when using a breadboard. It will create frequencies that will enter your body and cause damage. Wrap either the breadboard or your body in tinfoil to block out the frequencies. You must be careful with frequencies.

Does ur circuit works?
@@navamandco7251 yes it does. I’ve made it multiple times now!
Bro are the Resistors in Kilo or not?
@@prometheusn0ir its different. 2 resistances connected with the capacitor through pin 2 and 6 are in kilos, but other 3 are not.
@@prometheusn0ir I struggled multiple times but now it works Alhamdulilah. And now I have made it multiple times, it always works fine!
Only green led still glowing 😮

red yellow green, yellow, red, project is from red to green without yellow
So nice thanks the world's best teacher

Well, didn't understand and i guess others didn't too
@@spthepero2282 That's the sequences used her in the UK, it's been that way for 30+ years
In the stats, it's just like this video.
Tips for doing this but with timed relays outside the bread board?
It works better than my city traffic lights xDDD
bro do u know how to calculate the resistor and capacitor for this times?
green: 4 sec yellow: 1sec red: 3sec
Can we have the simplifications for this project, like the truth table and K-maps?
Bro I connected the circuit (copied every instruction) 8th time still I'm not getting the proper output, my led is not glowing, can u pls help me with this .
What bro yasash go figure it out by yourself bro
Excuse me, what causes the first lamp to turn on, the second to turn off, the third to turn off, the second to turn on, and the first to turn off, and the third to turn off?
sir i did connect the circuit the only proplem green light didn't glow why
Very nice. I'm going to have to breadboard this myself.
Does the resistor need to be specific?
What to do if red and yellow led are glowing together???
Redo everything
Is it advisable to use a 9 volt battery instead?
😅😮😅😅😅well ingormeti0n.Good show more 😅😅
A modified version of this would be really cool in a miniature build or something.
My art hobby and electric engineering hobby parts of my brain are becoming friends and it's scary.
what is th volts of capacitor did you use?
How to give power supply a battery of how many volts shall be used ?
Can we add 7 segment display here?? If possible kindly say the instructions
Green and red LED glowing, but yellow not glowing, y..? Pls explain
Did u figure it out? Please tell
Same problem
Hi
I'm having the same problem
If you found the solution please reply
Sir thanks so much
Good job
I made the circuit but the yellow stays on, that is, the green lights up, then the yellow lights up and when the red lights up, the yellow stays on, why? Thanks and congratulations for the video
How do you make it for UK traffic lights?
much cool if this have a 7 segment display
Do you have the circuit diagram for this ?
how about every after cycle, it gets back to yellow?
What's the logic gate for this?
Should always passing the yellow warning
Oru upakaram ela tto😌
Also make it on a PCB board.
Will try bro
Is it working in astable mode or monostable mode?
Astable mode
Awww, it does not go back on yellow (nor dies the red and yellow together glowing, that a real trafick light would), it just cycles back to green!
Traffic lights dont use yellow before going to green. They only use yellow when going from green to red. At least in the united states… though there may be some state that uses the yellow light to transition to red or green i just don’t know about.
@@pikadroo Traffic lights switch from red to red and yellow, and then to green. The red and yellow phase is missing.
In the states it's like this video. Green > Yellow > Red > (repeat)
super video ......
Do you have a video about it on PCB?
The capacitor is 100 uf, what specific Voltage?
You can use 100uf 50v it will work
25v is okay
How to calculate the time delay of tht red led???
What will be the resistor value for tht red led?
late to the video , but i don't understand why do we use a resistor between output (pin 3) and threshold (pin 6)?
it regulates the frequency
Can you send me all instruments name what we received for this project plz send today
Can we get the circuit diagram?
Can why the yellow led is not glowing in this video
Vídeos como estos son geniales
Dont you have to program the 555 ?
No
can i use this battery?? Generic HW 6f22 29312 Hw Long Life Zinc Carbon Battery, Hi-watt, 9v
yellow led glowing with green Led what to do ?
Sir 100uf capacitor koto volt er
100uf 50v will work
Sir any other alternate resistor?
انا قمت بتجربة هاذي المشروع ومعي الضوء الاخظر ضعيف لماذا
Yellow led glowing only one time in this video and my circuit too why so
What is the seventh pin not used in the first 555timer ic?
Yes not used
@@Creative_Experiment what is the reason ?
Me gusta más el 556
My led is not working
