    Why do you make videos with background music, you could have explained the working of the circuit both on circuit diagram and final wiring. Popups are overlapping the circuit diagram. You can share the circuit diagram in description also.

    Hello everything is fine!? Well, I did this project the same way you did, but with 1 red LED and just one blue, and everything worked fine. However, the blue LED burned out and the red LED only remained on not blinking. I added another resistor and the LEDs blink more slowly. Can you explain to me why the LED burned out? I did it the same way and components according to the video.

The problem is that the normal light is flickering like in the video sir, only the red and yellow ones are in each lane... the blue and green are off (not on) even though they were tested one by one with all the multimeters. it's on.. why, sir? What do you think is the cause? Please guide, thank you

    • @JaviersDIY
      @JaviersDIY  Год назад +1

      yes sir that's correct but as what I have mention earlier, the input voltage of that LED is dependent on the color and quality sir. For example the color red LED has a support voltage of 2.5v maximum while the color blue LED has 3-4V that can support meaning it has a big comparison with the color. I suggest just use the same color
