Green Blinkenlight: Creating a Simple Clock Circuit with a 555 Timer

We create a clock circuit with a 555 timer in astable mode, and use it to blink a green LED.

blinkenlight, noun
- A flashing light or beacon light
- A status light on a electronic or electric device such as a modem, router, network hub, and so forth

Oh my god thank you! I tried everything and then noticed that the 555 timer was the wrong way

Thank you very much. Very clear and organized presentation

Hi
Sorry for the stupid question.
I manage to let this work on a breadboard.
I didn’t have exactly the resistor and the capacitor but I managed to find the right stuff.
So I tried to put on a strip board but I’m noticing something weird.
I didn’t use the small capacitor that you used but it was fine on the breadboard.
Consistent light and good range of oscillation.
On the strip board the led emit a really low light before actual blink, I can notice when it’s really slow.
As I said on the breadboard don’t happen but I copy the same circuit.
Any help?

Thank you

nice detailed video, do you take on design jobs - need a pcb board designed

Can someone pleas explain this to me? For weeks, I have been trying to get this circuit to work: setting it up in this *exact* manner. But, the discharge never occurs. The output will get stuck low, but the capacitor will never discharge. Is it possible my IC is damaged somehow? i have tried just about every possible configuration, using a physical RA and RB, using a potentiometer to represent both, using an electrolytic cap instead of a tantalum one, but the exact same thing always happens: Output goes low, cap voltage charges all the way up to Vcc. I know it must be some issue with the path from the Cap through Rb to discharge but I can't figure it out.

What is the ceramic capacitors value?
I am trying to remake it but I think I have the wrong compacitors

the video is great, though i think your voice could be a bit louder

using 3 ceramic capacitors, is just a waste of money.
