Model Traffic Lights Circuit | 555 Timer Project #15
HTML-код
- Опубликовано: 10 сен 2024
- A tutorial on how to make a model traffic lights circuit using 2 555 timer IC's and a few other electronics components. This circuit turns ON green LED, keeps it ON for some time, then turns ON yellow LED for a moment and finally turns ON red LED for almost the same duration as the green LED. This cycle again starts from green LED.
Explanation of how this circuit works is also included in the video.

Components Required
* 2 x 555 Timer ICs
* LEDs: 1 Red, 1 Yellow, 1 Green
* Resistors: 100K, 47K, 2 x 330R, 180R
* Capacitors: 2 x 100uF
* Breadboard
* Few Breadboard Connectors
* (5-12)V Power Supply

Works Properly Elonics never shows fake videos
For what value of resistor and capacitor the time period of led is???
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.
U made it on breadboard or zero pcb board?
@@BareenaDeshmukh I first made it on bread board and now I’m shifting it on pcb. If you need any help, I can help you out. Because this little thing took me days to get solved and was a constant headache. So I don’t want anyone else to go through that😂
@@Emm-i1z hey, were u able to solder the circuit on pcb board. Is the circuit working properly?
If yes, can u plz share the PHOTO(front&back) of ur circuit made on pcb. I am struggling to solder....plz help
Hi! I’m sorry for the late response. I also faced some problem with pcb and it did not work on that.
@@Emm-i1z hey bro do you have pcb layout of this?
Yellow led is not turning on...what should I do?
Same problem
Just to warn you, be careful what capacitor voltage you use. I used a 35 volt capacitor and it destroyed the 555 timer. This guy used 16 volt capacitor. Just a heads up
If i use 25v capasitor, it's safe?
Thanks! This really helps with my homework.
Mine doesn't change
It only light at green led
Hello Sir. Can you tell me how many seconds the leds are on? Example Red 8 sec / red and yellow 1 sec / 6 sec green / 1 sec yellow / and again red.
Good job it really work if you maintain resistance
Bro my circuit was working properly as shown in your vedieo but after keeping the circuit on for 5 minutes only Red and green leds are working yellow is not working i changed the ics but still yellow is not working whats the problem
My too this
When we are struggling to make our project and an Indian comes to save our life:
Sorry, a project with hall sensor as switch on off, a trimmer for setting time and pin 3 exit connect to relay or mosfet?
For quick shifter diy
Time frima 50ms to 100ms selected to trimmer or dipswitch..
Thank you if this requires its possible
(sorry for my bad English)
Hello sir, I have a question. If I want to use BCD to display time of lights in this circuit, what should I do?
How can I increase the duration of green LED after receiving a certain signal without disturbing the next cycle?
Can someone explain where we connect the ends of the yellow LED?
If I wanted to do this using a common cathode RGB LED, is that possible? Please advise!
how would one replace the mini black things with a full sized timed relay?
Good working circuits thanks brother
Hey add 3.3k and 100ohm resistor in series with the 2nd capacitor,since when i made connection i faced problem of both red and green led are on at the same time but i tried above solution by increasing some resistance of 2nd capacitor from pin 2 on 2nd ic and it works perfectly
Which resistor you have used in green led and where you used 180. Resistor
I don't have the 100k and I'm using two 47k instead do you think this is the problem
My led is not working but why.circuit connection has given in the same way
Help! This is a useful video and I set it up on the bread board and it worked fine, I want to use this on a model train where the input voltage is 24v. I set it up with a bridge rectifier and an LM2596 buck convertor so I can trim the output voltage but it doesn't work.
Any idea on this would be appreciated.
This video is very helpful..! ✨✨
ACTUALLY I WANTED TO CONVERT THIS CIRCUIT TO A PERMANENT ONE AND CHANGE IT TO A GENERAL PURPOSE PCB BOARD CAN I GET ANY SIMPLIFIED VERSION OF THE CIRCUIT
What is difference batween in ...normal traffic light circuit and this traffic light circuit using 555 timer ...??
Thanks a lot.
Bro.. sportztourer is your channel too?? Very similar voice, very technical information and explainationals.. I'm confused
Which transistor is used in this circuit?
I want to create the same circuit but I don’t want it to repeat how can I do it?
What is the software that u use to make the diagram?
Where can I buy the components?
All three are swithcing on???
What is the maximum voltage this circuit can withstand?
Yellow led Nehi jol Raha hai
How can I control the time of light?
Has anyone solved the issue with the yellow light not turning on? It jumps from green right to red. I see a few others have had the same issue.

@@Emm-i1z still ylo light not working
Why is only my red cutting on?
It doesn't work all leds light at same time
Should Always passing Yellow Warning that's the right sequence
Hlo red and green leds are ON but yellow led doesn't GLOW ,pls help
Same problem .. got any remedy ?
What to do if yellow and red led are glowing together??

Can you send me proteus file @@Emm-i1z
Made this circuit..only goes back and forth from green and red..yellow never turns on
Same
Same
follow the "schematic" by yourself, i was able to do it and so can you
list of apparatus used please??
i think you should reduce green light resistance in order to get more brightness
i am iranian
love you
Nice work thanks for sharing
Can this circuit work with 12V ? Thank's
See. 2:14
Oui, jusqu'à 15v. yes, 15v.
Bro how many volts battery is needed for circuit
9V
Mantap dan keren 😎😎😎😎😎😎😎😎
I built this on a PCB. When I hook up power, the green led goes on for a while..then it goes off...none of the other LEDs go on...and then the green comes on again.... What should I check? Thank-you
I think the second 555 ic is not powered/configured properly. What is the voltage you are using?
I am also having same problem.I am using 9 Volt battery.
Could u send me this on multisim
I can attach time as also
List of materials please☺️
are you joking?! just read the schematic...
Very good, friend!
Thank you!
👍
SHOW...👏🇧🇷👏🇧🇷👏🇧🇷👏🇧🇷👏
For those who are having a problem with yellow led suddenly not turning on, try to follow the "schematic diagram" itself and do it to your own breadboard. it works for me now.
Do you have the correct schematic diagram po?
@@jemalynaustral ung binigay nya mismong diagram ung sinundan ko
not ung nilalagay nya na sa breadboard
Sinundan ko Yung nasa schematic diagram,Ang ibang LED Hindi Kasi nag iilaw
Do you have a schematic diagram ?
Ok ok ok
List of materials please ☺️
Its in description
