Hello and good day! Thanks for recording and uploading this wonderful tutorial, it helped me out a lot. Though one piece of crucial information that was kind of missing was the complete list of the names of the pins. They all have numbers, but I had trouble following the tutorial because I wasn't sure which pin has which function. For anyone facing the same hurdle, here is a mapping of all the pins to their names: 1 => Ground 2 => Trigger 3 => Output 4 => Reset 5 => Control Voltage 6 => Threshold 7 => Discharge 8 => VCC

finnaly. guys, dont follow any other ne555 tutorials. this is the ONLY FRICKING ONE that works. istg none other worked. tysm im tryna find a working one for months. Your the TOP G fr. even without the capacitors on the power rails it still works

It's the first tutorial that actually worked ! I even tried to follow the data sheet, but with the components I had and the way it's written, I just couldn't make it work. Thanks a lot

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

hello Ian i hope this helps but I used to have dry skin on my hands, especially on my fingers, which would often bleed if I played basketball or lifted something heavy. I no longer have this issue after conditioning my hands to develop a tougher skin layer. My approach was to gradually heat up oil and carefully apply a small amount to my hands, repeating this process and slowly increasing the temperature over a few months. I was also a cook at a restaurant for a while, handling hot pans and similar items, which further helped in building this resilience. By the end, my hands became much more durable, and the problem was resolved.

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

Something my dad told me, i had an issue with a circuit i made and he told me to put a large-ish capacitor (maybe 1k/2.2k ųf which is what i use) between the supply and the entire circuit. Suddenly, the effects of what i got from my breadboard is happening on the circuit board, which is what i wanted. Try that, maybe you just have a current shortage and need more available current, idk but good luck though

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

@IanWard1 Жыл бұрын

Looks like a 1uF cap connected to pin 5 instead of the 0.01uF recommended, and it's connected to Vcc instead of ground. The decoupling capacitors I used are 0.1uF. These are just capacitor values I had lying around that seemed to work. If you know how these values should be chosen let me know.

@@cesarhuerta9632 connecting to Vcc was just an accident that I didn't notice until editing the video. Seems to work fine either way, though so I've left it.

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.

This video series assumes an understanding of basic digital electronics. Ben Eater's videos are great to start with if you need to brush up on the basics kzbin.info/aero/PLowKtXNTBypETld5oX1ZMI-LYoA2LWi8D Also check out this great video with lots of background on the 555 chip from ScienceOnline kzbin.info/www/bejne/aqrckIqhbd-ir6c
