Simple Traffic light using BC547 transistor.

Simple Automatic traffic lights 🚦can be made with just a few electronic parts 🤗

🚦 Everyone knows that traffic lights come in three colors - yellow, red and green. A red light means your vehicle needs to stop. Yellow means you're ready to stop, while green means you can keep going.

NOTE : You can Increase/Decrease the timing of Red,Green and Yellow wire glowing by changing the values of capacitors.

🌈bring it on! Let's experience the fun of DIY together.

✏️ Below is the part list for project Simple Automatic traffic light.

1) Transistor BC547 ( 3 Pcs ).
2) Resistor 1K ( 3 Pcs ).
3) Resistor 100K ( 2 Pcs ).
4) Resistor 33K.
5) Capacitor 100uF ( 2 Pcs ).
6) Capacitor 150uF .
7) LED_ Red_Yellow_Green.
8) PCB Board.
9) Jumper Wire.

It is the best and simplest traffic light circuit. Congratulations on your excellent work my friend. 😊🇧🇷

Do you have a traffic light schematic diagram in breadboard but using 555 Ic?

Hello. Finding it difficult to find a 150 mf cap. All my cap kits go from 100 to 220 mf. How adversely will a 220 mf substitution affect the led timing? Thanks!

Hola se ve fácil y económico de realizar. Lo felicito.

I cant find a 33k resistor. Would 47k resistor be a fine substitute?

[mfadilahkamza]

can you tell me how each component works

[suzantalat]

Where can i find pdf file for this project?

[josephleria]

Should Always Passing the yellow warning lights that's the right sequence

What we need is smart street lights. With computers now a day they should determine how long and which lanes should be on and by doing so diminishing long back ups. Also add traffic jams occurring all over the city would be greatly diminished.

Nothing is working, tomorrow is last for my project submission, tried & got tired of testing all theese circuits.I m simulating in live wire(software for electronics & electrical circuits simulation), but no circuit is working 🥺

[isitoone]

I`m make a circuit working successfully..!! :)
