THANK YOU SO MUCH!!!!! I FINALLY LEARNED HOW TO CORRECTLY MAKE THIS CIRCUIT!! Before this, while I was using a software to simulate circuits, I probably built up an entire graveyard of virtual exploded capacitors, but with this tutorial, everything finally worked properly!

I have searched in what seems to be everywhere for a strobe light for my record player but cannot seem to find one, and thanks to you I've designed a 60Hz 555 circuit to handle it for me! Thank you so much for the video my friend!

Mate you're a legend. I was getting a headache looking at poorly drawn circuit diagrams on the datasheet!

These step by step instructions are very helpful. Thanks for the upload.

Enjoyed this video and the explanation of astable mode for the 555 timer looking forward to seeing more videos like this thank you.

Concise and easy explanation. Thanks, it really helped.

Really good walk through of how to set up this chip. Great job.

Thanks A LOT!! Now I finally finished the project me and my dad started when I was youger. We tried to make a set of turn signals for my Pedal Go- Kart!

Thank you so much!! This detailed explanation helped out a bunch!!

Thank you. You can really get it blinking by putting the negative side of capacitor on pin 1 ground and the positive side to pin 2 :) also you do not need any jumper wires to the rest At least not with my 555 timer I'm using the Texas instruments NE555P timer. I think each person has their own way and finds it. This is a great introduction video on the 555 timer GREAT JOB, and I love watching your videos.

I just did a search for 555 timer and got this one 70K views congrats

Best explanation I came across with practical explanation. I was scratching my head that why the hell there are so many resistor around the pins 6 and 7. Thank you Sir

Gracias x su vdo. Si alguien no comprendió del todo este vdo le recomiendo vea primero los componentes internos del 555. Cuando los vea se dará cuenta de que tiene que tener conocimientos de: 1) Divisores de tension. 2) Circuitos RC. 3) FLIP FLOPS. 4) Amplificadores operacionales, función COMPARADOR. 5) Transistor NPN. 6) BUFFER. 7) Resistores tipo PULL UP y PULL DOWN. 8) Saber qué es frecuencia. 9) Saber qué es pulso. 10) Saber qué es onda cuadrada. Si comprendemos lo anterior, podremos utilizar de manera asombrosa este integrado. Saludos desde Guatemala. I LOVE THIS VDO.

very helpful!!!

Prefect just what I was looking for...

Thank you so much, it worked

i just found this video after seeing that other one with the variable resistor, now i have what i need to make this circuit thanks to your upload. i subscribed. you make good videos. thanks.

Good video

Hello! Complete newbie here. I've found another video with the same exact diagram except for two components: the capacitor is 4,7 and he linked a speaker instead of a led in the same position. As result, the guy in the other video has the 555 to behave like an oscillator. Myself, having a 47 capacitor only at the moment, had a kind of metronome as a result. (It means: I did exactly as shown in your video and I got the same result). Is the capacitor 10x smaller to prevent the 555 to behave as an oscillator?

Thanks man helped

Instead of sending the RESET pin to ground, would simply removing it from VCC prevent the chip from outputting without damaging it or doing abnormal things? I want to use both sides of a 556 timer, each connected so that one side is in monostable controlling the other side in astable.

Amazing

Can you do a video where you use a potentiometer instead of the 2 resistors?

So connecting a capacitor from pin 5 to ground and adjusting the resistance values should give me a less than 50% duty cycle output right? Trying to use this to trigger a Mosfet for a converter.

Just what i was looking for! Do you have schematics

is it possible to wire the output from this timer into a CD40106 inverter to make it light up on the low and turn off on the high? Also, how would i change the amount of time that the LED is off or on?

Is this can power up little 180° servo forward & back continuesly without any button?

Please Can you make bell door electronic multi tone .and sound of bird used the i c 555 thanks for you .

Wow!!

hey my friend I need to make a square signal that have not any small changes in frequency or pulse width but ics like 555 timer can not be like that and have small changes is there any way???

Hi there, Is it possible you can give me the circuit diagram you used? I can't seem to find it on your website.. I'd appreciate it a bunch

can we use different resistor values ???

I had to giggle as when You mentioned You had forgotten to jump the Pos and Neg rails on other side of board because you usually use both sides as I also prefer doing myself ,but i wondered how long it took You to figure out as in my case it was hilarious as i was making a remote circuit with a relay , 2 transistors, 2 leds ,resistors , 1 relay and a cd4017 and i could not understand why the LED would not light up. I was building it from a Schematic I found on You tube and I knew it was suppose to work and each time it failed no matter what and every time i took each components out and rewired everything about 5 times over 2 hours till i realized i only had power on one side, while most of the required voltage was suppose to come from the right and all along ( my preference) but i had forgotten to put the Jumpers in. so I had to laugh when at times most of the mistakes I made were lack of common sense which is too familiar to me lol.

Is it possible to use this with many LEDs? If so, how?

hi! do you have the schematic of this circuit?

There is a way of calculating the frequency of an astable circuit using a chart called a nomograph and cannot find any explanation of how to do this and would love to see a video with a step by step explanation of how to use this chart.

nice,but you dont mention what type of diode and no schematic

Hlow can everyone help me how Ican make timer work five second I wont use for airbag light for my car

Show schematics pls

NOT Reset is pin 4

Good video
