Traffic Light Circuit Using | 555 Timer IC | Led Projects. 

It works better than my city traffic lights xDDD

Very nice. I'm going to have to breadboard this myself.

Only green led still glowing 😮

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.

Tips for doing this but with timed relays outside the bread board?

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.

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)

super video ......

Sir thanks so much

bro do u know how to calculate the resistor and capacitor for this times? green: 4 sec yellow: 1sec red: 3sec

much cool if this have a 7 segment display

Is it advisable to use a 9 volt battery instead?

Can we have the simplifications for this project, like the truth table and K-maps?

Does the resistor need to be specific?

sir i did connect the circuit the only proplem green light didn't glow why

How do you make it for UK traffic lights?

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.

😅😮😅😅😅well ingormeti0n.Good show more 😅😅

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?

how about every after cycle, it gets back to yellow?

Can we add 7 segment display here?? If possible kindly say the instructions

😮

Oru upakaram ela tto😌

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.

.could someone maybe send the link for a good electronics set under $80,

Can we get the circuit diagram?

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 .

can i use this battery?? Generic HW 6f22 29312 Hw Long Life Zinc Carbon Battery, Hi-watt, 9v

Should always passing the yellow warning

late to the video , but i don't understand why do we use a resistor between output (pin 3) and threshold (pin 6)?

Can why the yellow led is not glowing in this video

Thank You 😂

Can you send me all instruments name what we received for this project plz send today

Sir any other alternate resistor?

How to do 4 way traffic system using ajrdino nano

Think it would be easier to build with an aurdino mini.

Also make it on a PCB board.

What to do if red and yellow led are glowing together???

It works

can anyone explain the connection of these 3 LED in this project...

Do you have the circuit diagram for this ?

yellow led glowing with green Led what to do ?

How to calculate the time delay of tht red led???

The capacitor is 100 uf, what specific Voltage?

Green and red LED glowing, but yellow not glowing, y..? Pls explain

Yellow led glowing only one time in this video and my circuit too why so

Is it working in astable mode or monostable mode?

What are the materials used here? pls anyone answer we need it for our school project

Hii sir i also make this circuit on breadboard but only green led glow

Sir it's very urgent....pls send circuit diagram

I can get a diagram of that system

Sir plz send it's circuit diagram

Hi , good job can you help me about create a small project I need some information I’m new in it

What is the seventh pin not used in the first 555timer ic?

My led is not working

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!

Dont you have to program the 555 ?

انا قمت بتجربة هاذي المشروع ومعي الضوء الاخظر ضعيف لماذا

Circuit diagram

Please give the circuit please

9 volt battery chalegga

Sir plz send circuit diagram

Sir 100uf capacitor koto volt er

What's this music called ?

Anybody send ppt for this

Components Name list ??

Circuit send panunga

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.

PPT dedo please

Please reply

نينينينيني

The yellow phase between red and green is missing...

pw nya mana kocak

didnt work

Walang kwenta pa palit palit ng position ng cable

Doesnt working . Wrong video

You change the connection of light 2:09

Sir plz send it's circuit diagram

Sir please send circuit diagram
