This is a very good and simple tutorial where I built a system specific to my needs and made little adjustments just as it was explained. Thanks.
Very nicely done! You were very thorough and clear about the process and the science behind it.
Thank you for your excellent tutorial video! I followed along with the video and was able to produce a functioning circuit. Even better, with the links provided in the description, I was able to tailor the blinking rate to my particular needs. Best electronic tutorial hands down.
This is the best explanation ever. You've explained it best. Thanks a lot. God bless you.
Brilliant. I am totally new to electronics and I am starting late on in life. At 45 years old with disability and poor health. I have just recieved a breadboard kit and this video is so simple to understand that I can follow it. Thank you. Ken, near Wigan UK.
Very good video. Nicely done, with circuit drawing and explanation. And no annoying music. Good work!

nice one and active channel
i m immpresed that u r answering questions fast
Very informative video. Thank you for this excellent tutorial video using 555IC.
finally, a person who explains why & how to, thank you
THANK YOU THIS HELPED ME WITH MY ENGINEERING HOMEWORK :'))
Great video. Will probably get a cheap 555 timer or two soon :)
Best video about this course I've seen soo far. I'll recommend my mates to come watch your videos😊
Thank you for such a good explanation !
very nice and simple explanation..good job
Nicely Explained Much appreciated 👍
This was gr8! For some reason or other, I often have problems with getting these 555s going, but using your circuit, I got the thing working 1st time. Your presented schematic is very clear and easily understood. Another issue is the mark space ratio, the amount of time the output goes high, in relation to it going low. I'd like to know how to improve this to make it 50% - 50%. Another issue I found is, if you've an FM radio nearby, it will stop receiving but instead will give out a broad band RF signal, which swamps the nearby radio, giving out a loud 'rushing' noise. This can be corrected by a 0.01mfd capacitor connected between pin 5 and ground (negative), I have found. It may not be a problem if working from a battery, though. Thank you for uploading. (o:
Works great, thank you.
I knew capacitors in parallel increase the capacitance, I knew resistors in parallel reduces the resistance. You just made me understand how that affects the LED flash rate with the 555. Thank you sir! Subbed. Be safe, good man. 5/9/20.
You're welcome :)
Stay safe!
Thanks for such a useful circuit with full information, I need some unique case, on for 0.5s and off for 2 or 3s and so on.
thank you for explaining
Thank you for explaining what each piece does. A lot of the videos on here don't explain how it works they just put it together.
+Anthony Proctor You are welcome !!
+Anthony Proctor i was going to say that to
Video made clearly, i'm going to try. Then i reply result. Thank you its working and again thank you so much...
Thank you ..that was v good explanation. G Job .
I expect this type of explanation...well done 👏

Excellent tutorial; You got a sub!
Brilliant. Great explanation. Thanks
Can I add multiple LEDs to this circuit? Like 4 or 5, and if so what additional circuit adjustments must be made? Please and thanks.
thank u sir,it helped me a lot....
Very informative ❤️
great job!!!
Thanks a lot sir ☺️
Well done
Good Explanation...........it is very helpful for my practical project thank you so much......
You're welcome :)
👍 good job
I like this video, most of
the videos don't explain, tysm
Cool bro. We love you. Keep up the good work.
Thanks for this video. What values of Ra, Rb and C - and anything else but using the same 6V power source - do I need if I want the LED to be on for about 0.3s and off for about 3s? I could not use the equations to work them out!
Thank you sir
Very useful
Thank you very much
thank u.... u made my work easy!!!
+Daniel Lobo You are welcome !!
Thank you
Thanks all vedeos well.
Best explanation
awesome :D
Great 🙏🙏🙏
Very nice explaination brother keep going....
thank you for explaining your video clip very clearly.i am expecting 4x4x4 LED cube making with diagram thank you......
Good.Continue to add more circuits in Digital logic,analog op amp, and simple transistor based projects.
i love it
Great video. Very informative. I want to make one for using in my car with 12v volt input to the circuit. In addition to that as led I want to connect it to a particular led within the cluster. The led in that circuit requires 12v to lit it properly. What changes do I need to make in your circuit to fit my requirements. Will appreciate your help.
super video.
Thanks!
Nice! I'm a beginner, I have the circuit built, now I was wondering if there's a way I could make the high and low values differ from each other, I need the high time to be around 500ms and the low time to be around 2sec. Is that possible?
thank you
Nice diagram and good vidio and elplaction i like your all vidio nice vidioes make some new vidio ok i like your vidio and all the circuit are working .
Hi! I've been finding a circuit to build a led strobe. I just want the led to flash say 5 times in a second and then delay of say 1 second and repeat this cycle again.
Please help me
Thanks.
This is close to what I have been trying to find to make a flashing LED for a lighthouse I want to build. I would like it if I could get it to fade in and out though so it would simulate the "rotation" of a beacon. Any help would be appreciated.
thanks
If using the 12 volt LEDs can we skip the RL when power supply is 12v?
super
i am using 10uf with 16v but i doesnt flash at all.Or need to use 100v 1uf only can work?
Mine wont work, what is your voltage of your capacitor. Im using 1 microFarad with 16 V
my friend, what would my resistor values need to be for a 3.3V power supply running an LED rated at 3.3-3.8V @ 20mA?
Nice! Can you make one that shows a way to increase or decrease the speed of the blink using a potentiometer?
Just put a potentiometer there instead of Ra or Rb. If you have the circuit on a breadboard you can try different configurations easily.
I need to run four 5mm leds On 5v supply, what changes do i have to make. leds need to blink fast, i need this for my bicycle. Please reply.
hi bro...I have done the exact connections with the same reisiter n capacitor values as you have shown in the video.. but my led doesn't blink. it stays on ....I also tried replacing ne555 timer with a new one thinking it may be got fused .but no change..it doesn't blink. just stays on... please say wat needs to be done..
Could you replace Ra or Rb with a potentiometer and be able to dial in a specific flash time?
great.
Thank you so much, but i have seen circuits where the pin 5 was connected to ground via a10 nanofarad capacitor why is that ?
To dampen the internal oscillations if the circuit is to work on higher frequencies.
