POLICE LIGHTS Circuit. This circuit flashes the left LEDs 3 times then the right LEDs 3 times, then repeats again and again. This circuit is made with two timer ics
all detail is given in the video
Thank you for showing me this!
I received a kit in the mail.
No instructions & no schematic!
Now I know how to make it work. thank you!
New subscriber & a big thumbs up!👍

Hola saludos cordiales. Fueras tan gentil de indicar los valores de las resistencias, y de los condensadores...
Gracias.
Thanks for the share. Is it possible that it can stay lit and oscillating in this circuit? Stay lit mode and blinking mode?
Hi, this can works with 12 v car power?
good idea 💡 🌹
Cool thanks for the reply 😁
U are valuable for me
о... спасибо за схему, очень помогли )))

great, thanks for share !!!
thanx alo dear
Thank you for the share
thank you
on the first electrolytic capacitor at what voltage?
also on that side do you connect the positive?
i have used used 1uf 16v
use negative side of capacitor with point 1 and positive with point 2
Great project
thanku so much dear
Very Excellent 🌹🌹
Very nice idea🙏🙏❤❤
Hola, como hago este mismo proyecto para 12 voltios en DC, para un vehiculo, gracias
super !!!!!!!!!!!!
Perfect sir i will try to make it
thanx for watching my videos
How can you change the flash rate of the less? What would be needed to be added to control the flash rate or isn’t that something you can do?
Change capacitor only flash rate will b change
What size leds did you yoo?
How can I add more LEDs.. please suggest
How to make an electronic thermometer
Best of luck
I can’t see the circuit in the link you have given only ? Marks
hey.... i want to build this circuit but your link in the descreption dosn´t work
I'm working on it link will b open in 2 hours
thanks
Cool I might have to try to find the pieces put together to make one of these for my daughter's RC. Only question I have is if it will run off of a 2s lipo or 3s lipo
It will run on 2s , it you want 3s you need 3 leds in series not 2 as shown in video.
@@sffmail80 cool, thanks. I don't know a lot about LEDs, so I appreciate the info.
Just get a used police light of eBay for 20 bucks.
@@johnmadsen37 then where's the fun building it ??
Want to do this for rc car project. Can this support 24 LEDs? 12 red 12 blue
If we are not using 100nf capacitor its working or not??
Ótimo 😁👍👀👍
Sir can we use another resistor for this project if yes which one? Pls
can I do this with just two 3v COB leds...red and blu....it will work?
yes it will work with 2 or 3 leds which you want
plz visit my website for my promotion
www.envirementalb.com
Podria explicar los positivos y negativos de los leds por lo demás bien
puedes hacer lo mismo con led smd ? te agradeceria un nuevo video. muy buen trabajo enhorabuena. un saludo
querido puedo hacerlo con smd
pero como saben, la soldadura smd es muy difícil de todos modos, usted es respetable para mí
lo haré pronto inshaallah

Nice sir .
thanx for my encouragement
Can we run it with 5 volts ...instead of 9 volt
Woow super 👍
thanku so much for my encouragement
bonjour, je cherche un montage double flash sur 2 leds en simultanée
Nice project...
Thanx a lot

Good,,,,,
Very very nice
thanku so much for my encouragement and giving me like
Hey, buddy! How can I put 2 transistors to connect more LEDs and which should I use? Thank you and congratulations for your channel
thanx alot dear you can use transistors with point no 3 of both ic
connect 1k resisotor with point 3 of ic and then connect with it with the base of npn transistor
emitter poin to tranissotr should be connect with negative power and collector pooint of tranisots sould connect LEDS

@@gillanidata Very good, and thanks for your hard work. THANKS!!!!!
Спасибо за схему, лайк!
Can any translate it in English for my help plz
@@gillanidata he say "thanks for the circuit " it´s a sharp bye
Thanx dear
Just increase the value of capacitor to slow the speed
Name of music please.
Awesome👏 i can use the bike 12 volt
nice :) how to do this with 12v output for 12v cob LED ??
please help
Use 100mf capacitor.connect it parallel on supply.also use 270 ohm resistor on one pole of led connection.i tried and it works
You need to add a 10nF capacitor between pin 5 of the first 555 and ground, other wise the duty cycle is off. Same thing should be done for the second 555 , but the difference is not noticeable due to the higher frequency.
Yes u are right
But its done due to high volts
If I use more components circuit become complicated that is why I used short diagram
And thaku so much for my guidance and suggestion
@@gillanidata After your video I build it my self and ran into a few problems, thats why I'm giving so much feedback. One of the problems was exactly the duty cycle and adding the 10nf capacitor solved the problem.
The problem is not the lack of capacitor at pin 5. The problem is that leds arent current limited because a limiting resistor is missing. Because of that, voltage at the output fall down from 9V to 6V or 4V depending on what color is lighting. And because the 555s are connected in an unconventional manner, the duty cycle depends on the output voltage. Furthermore if there isn't enought output voltage, the 555s might stay steady. The capacitor at pin 5 helps to prevent unwanted transients when the power supply is loosy, but for low frequency circuits it isn't mandatory.
By the way, leds are being killed by overcurrent and connecting leds in parallel is a very Bad idea typical of an unexperienced apprentice. You would remove the middle nodes at the leds, add 2 series resistors, and the whole circuit will run much safer and longer.
@@mariobv947 well not quite, if you'll check this circuit is not influenced by voltage, it is typical circuit exactly for that issue. Also about the alternating voltage you are not right, I checked on oscilloscope and there is no such problem. The only way to obtain 50% duty cycle was the adding of the capacitor, belive I tried everything. About the over current I can say it ran all night whithout heating .

Bro how many volt of 1 uf capacitor
sa10-28-2023
(1.) Hi, there. Love the way you turned the 555 timer ICs to face each other; simplified things, for sure.
(2.) Using two different browsers and search engines, your LED circuit isn’t populating, can’t be seen.
(3.) Would you update for us?
(4.) Thanks.
(5.) Toodles!
but plz bro make it in easy..may Allah bless you dear..
thanx a lot for prayer and well wishing
Good
Thanx a lot dear

How to do this 8 diods?
these are LEDs dear
Hello, how could someone tell me what capacity are the 2 capacitors, many thanks to all for the help?
plz write in English
gillani data Hello, how could someone tell me what capacity are the 2 capacitors, many thanks to all for the help?
2nd capacitor is pf capacitor (104)
gillani data thanks and the first capacitor of what capacity is
1 capacitor is 1uf and second is 104 pf
How many LEDs can be used in this circuit?
as you want but if you you use more than 20 then you will have to use extra transistor
plz visit my web for full detial
www.envirementalb.com
mantap
thanx dear
Sir can you send me the circuit diagram of this
how do you connect the leds?
I have connected the LEDs in series
Where is the schematic? It’s only on the preview for about a second
The capacitor with 104 on it is 100nf; not 104pf.
Nice job btw.
Ye u are right
Thanx dear
104 is 100nf
It's not clear what the name of the component is,so I am not sure how to explain it.
OMG, I like this a lot!!! Anyone here wants to draw a PCB Board for me? I will pay you to do it.
dear I'm always with u
I send u PCB diagram in few hours
@Amar Bedi - He never sent me the PCB Diagram.
Mine is alive but not blinking,what is that from?
Same mine alternates but that's all. I used 4 chip cobs maybe that's why...
Sir pcb circuit diagram bna ky dy sakty hain plz
sorry for late ans

How to use 12V power
U can use 12v with this circuit
Вы с какой страны будете ?
Plz write in English
ok thanks. ...but also make a mobile signal jamerr...after the fm recevier
inshaallah
I will make soon
why not use 556 instead>
Rather have something bright enough to see in daylight out to 1/4 mile. A professional setup.
Use RGB light
Then u can see the light a miles away

Sir Im charging my 12 volt battery with charger having ampermeter can I know my battery full through ampere meter if yes how ...? Please make video on how to know battery full of 12 volt using ampere meter
U cant check ur battery perfectly through amp meter
Any how when battery takes more amp its mean baterry is empty
Amp drops down gradually as battery charge
And when battery become full it takes zero amp
Can or cannot check ... ?
Thank you sir ... Anyway in my 12volt charger I have amp meter 0 and 1 upto 6 amp and have tunner idicating 1 2 3 4 I hope these tunner.. is a controller whether to charge fast or slow . ? I charge my battery tunning into no. 2 and amp goes up to 2 above yes amp drop down to under 1 between 0 when I charge for hour but when I turn up tuner into. No.3 amp will go up 3 above again why is that I guess batery no need to charge again even if amp goes up when I just change tuning please reply ...
Can b checked
bulb kase lage ha bai
4 leds ulti oor 4 sidhi
