This circuit simulates the operation of a Traffic Light and works thanks to two ICs: NE555 and CD4017. The NE555 acts as a timer, while the CD4017 is used to drive the three LEDs. The signal generated by NE555 is sent to CD4017 which regulates the operation of the three LEDs. The pins 1,5,6,9,10,11,12 are the outputs for the LEDs, pins 2,3,4,7 are unused. The "Traffic Light" effect is possible thanks to the combination of diodes 1N4148 which manage the switching on time of each of the three LEDs. Finally I added a LED to indicate the presence of power, and a second LED to indicate the presence of the signal generated by the NE555.

hello,
What is the small pin /rod you attached to VCC and ground. I think you soldrered it as well. What is it?
sir which software u use to make the circuit i am using multisim ad i cant find the components NE555 IC and CD4017 IC
This is so beautiful to watch and learn. I am not at all familiar with the wisdom, but it is just incredible to see such cool work. I thank you very much for sharing your talent.
Hi, thanks for appreciating my work:)
Hai gayse traffic signals
I did. It happeded exactly as in video. It's very nice, instructive circuit/video. Greeting.
I am happy! thanks
Is this an Finite State Machine? Also can I make this using two NE555 ICs ?
Nice project. Good to have the UK light sequence 🤐
Sir/Maam may I ask what are the all in all materials been used?
Hello sir, may i ask you a question? which library did you use for this project? I can't find the 4017 part anywhere in my library, can you please tell me where can i download the part or even the library you use sir? thank you..
Hi, no library, the CD4017 is an analog IC
Very nice looking board.
Thank you:)
Excellent video Ty..!
Thank you:)
Deat Stefano please can you tell me what kind of nf-capacitor you use and where I could get the same of them? Thank you and kind regards!
Hi, I used 1x 47uF Electrolytic Capacitor, 1x 1nF Capacitor, 1x 10nF Capacitor, you can try searching for them on LCSC
Okay but can I use ceramic caps or do I have to take another kind like polypeopylene caps..? Thanks again!
You can also use ceramics the important thing is that you respect the values of my scheme
Awesome work🇧🇷🇧🇷😉👍👏👏👏
I really liked your project the PCB board, which was perfect, really beautiful, and I want to congratulete you, but I noticied that during the operation of this circuit, the yellow LED lit up when changing from the red LED to the green LED. Is this correct in your country?
Hi, thank you!
Yes is correct, I have chosen a type of traffic light that I would like to have in my country as well, in order to warn the driver that the green light is about to turn on like this: th-cam.com/users/shortsi6ubteR2p04?feature=share
Ok. Here in Brazil the yellow LED only lights up during the change from the green LED to the red LED. But thank you very much for your attention, my friend.
HI! I know I am watching this video a little late and you are most likely not going to see this. I was just wondering where I could get everything not including the PBC boards. I have them in the cart, I am just having a hard time finding the other supplies.
Hi, the new comments in the old videos I see them from the TH-cam studio;)
I get the components in several places, for example amazon, banggood and aliexpress.. I also bought them in electronics fairs before they suspended them all due to covid :(
Thank you so much! This was very helpful!
This is probably a stupid question but I am learning. How does the red LED stay in when the yellow led comes on. It only seems to receive 1 clock pulse. Also what are the diodes for? Red led doesn't have one. Is there a reason for this?
(great video. I subscribed)
Hi, it's not a stupid question :) The IC CD4017 has 10 outputs that they give an output in sequence, and the frequency with which they give an output is generated by NE555. The diodes are used to convey the various ignitions to create the traffic light effect.
¿Circuit In The Breadboard?
It was an amazing video, thank you so much. I just have one problem, i want the signal to alternate between red and green with the time gap of 60 seconds, what changes should i make to achieve that, please help me out sir. Thank you, hope to receive your response soon.
Hi, thanks for appreciating my work.
it is possible to change the speed of the LEDs by adjusting the frequency produced by the NE555 by changing the 22K resistor (the one between pins 7 and 2) .. but this would change the speed of all 3 LEDs, unfortunately it is not possible to change only the green and red LED speed with this type of circuit.
Look up flashing leds with a 555 timer , that’s all you need to flash two leds.
@arduinomaquinas, thanks you 😉🇧🇷
hi, i want this pcb help me
Hi, super nice video! Imagine I want to make the same, but with bigger lights. What should I adjust? Thank you
with bigger lights I meant lights that require more power
Hi, to connect lights that require a lot of energy, there may be 2 solutions:
1) Connect power transistors instead of the LED to amplify the current output from the circuit.
2) Pilot 5V relays which will then pilot the bulbs you want to connect
@@Stefano91ste thanks for the quick answer. Same input voltage is applied?
Yes the same!
Which element should be changed to achieve different speed of changing lights?
The values of the capacitors or resistors should be changed to achieve different time delay values.
The delay is controlled by the formula T= R*C, where T is the delay, c is Capacitance and R is resistance
Thanks for answer. What maximum current is available for control 5v relay? Will this board work with such relays?
Hi, it is possible to change the speed of the LEDs by adjusting the frequency produced by the NE555 by changing the 22K resistor (the one between pins 7 and 2)
Could you add more leds to each output if so how many per channel would you recommend thank you great channel
Thank you very much, you can put a maximum of 3 LEDs per channel, after this, transistors will be necessary to amplify the current for more than 3 LEDs per channel
@@Stefano91ste Thank you Setefano for your reply
Would you be able to design a gerber file incorporate the transistor to run 10 leds for each colour so 30 leds in total
Many thanks. Dace
How much does JLCPCB pay you to sponsor them? How about if you explain what a gerber file is, and also indicate what country JLCPCB is in. No use dealing with them from the US or elsewhere since shipping would kill the deal.
Hi,
- A gerber file is simply the format of the file you export the PCB to. it is actually used for the production of printed circuits, to trace electrical connections such as tracks, copper layers, solder mask, legend, drill data, etc.. The gerber file contains information for drilling and milling the PCB. These files are generated by circuit routing software (I use sprint layout 6) and are sent to PCB builders to be loaded into their machinery software to print PCB.
- JLCPCB is in China, I have no idea what US taxation is like.
- Regarding sponsorship it is not a topic that can be talked about, are confidential things :)
Regarding the gerber files I will make a dedicated video with some extra information!
Can we use in4007 instead of in4148?
Yes, of course
@@Stefano91ste thank you. respects.
Trafic light for 1 lane only?
Yes, it simulates the behavior of a single traffic light
🤔 falto algo muy importante¡¡¡🚨🚨🚨.
El potenciometro de ajuste ( adj. ) time.
Y el enlace de TX. Para cambiar el Adj. Tiempo en el semáforo a distancia.
Pero por lo demás bien.
Saludos desde Chile 🇨🇱👍
También la posibilidad de sincronizar con otra PCB similar
diode magic xD
Thank you:)
does jlcpcb supply parts
They have LCSC for electronics components
Porque no permite ver el diagrama ?

Hi. Can you show this project on Breadboard, please?
I will do it :) why do you want to see it on breadboard?
Precision drivers seems like overkill...
Ye kase pata lagta ha ki muje is project m itne number ke resistor lagane h project m please solve this problem and send me
Hi, I didn't understand what you want to ask me
@@Stefano91ste mera khne ye matlab h ki jo apne project bnaya h usme jo apne resistor capacitor lagye h apko kse pta ki isme itne ohm ka resistor or itne microfrad ka capacitor lagega
@@Unemployedcreator786 ne555 timer output based on resistance and capacitance. There are lot of app which can shows u which frequency is output if u put a reaistance or capacitor
Hello Sir
Can you show cement level circuit please.
Cement level? what do you mean?

Good job!
