FULL BRIDGE RECTIFIER !!!! ......., Thanks electroboom for this stuck in my head.
BOOM! -Taras Kul
Thanks for the really great tutorial!
I think your explanations are spot-on. You explain exactly what is necessary without going too much into basics or advanced stuff!
Thanks, I finally have a good understanding oh how triacs work now. I've watched a lot of videos on them and mimicked the circuits but never fully understood. So simple.
I have been searching for this video for too long, because i didn't know how to use a Triac. Thanks!
Saw many videos related to this topic, and this is the one that made me understand, great explanation, oscilloscope and edition!
This channel needs more subscribers! Great tutorial paired with common sense.
Hudson Chamberlain thank you so much!
Thanks for making such kind of video, Today I have learned how to control AC voltage
awesome !! great video as always :) this is the video for which i was waiting for. keep it up my friend
Great pedagogy! instructive video indeed. And your accent adds an awesome exotism to the whole ;)
Thanks bro, your videos help me alot. I am currently in college, once i graduate (hopefully in 8 months) ill make sure to fund you on patreon.
Really Nice finally i understood how to make dimming controller device
Great explanation Electroboomnoobs
i just gonna fall in love with you when you say FULL BRIDGE RECTIFIER :D
congratulations another beautiful tutorial
Great explanation! I got a little nervous when you were pointing at the high voltage components with a metal screwdriver.
Excellent video.it was useful to me.thank you so much.
Fantastic work, man! Really, really nice! 😀
Thank you, I now understand trials.
Such a good tutorial. You could be the professor
That were too good... Sir... Thanks for this video
been waited for this , great !!!
very nice project also presentation. thanks
Nice video and good explanation, thanks for share
Maaan ! a lot of knowledge , thank you so much !!
i like him . because he give answer of our comments
I ve enjoyed a lot
Keep going bro
Great job sir, nice project
Nice and knowledge full video bro thanks dear
Good project for smart home.
wow this is what i'm looking for thanks.
Love your way of clarifying the concepts behind your project. You mentioned briefly that you can use step down trans say 230/12 volt. Is that mean that if I provide 12 volt to your circuit all the components will function with NO CHANGE. of course I will use an LED as a load instead of the 220 volt lamp.
great work Dude...
Excellent dear
The banana is not for sale, it is to let you compare the sizes of the items near it. I think that is what he means when he says it is for scale. ¿Pero que sé yo? (but what do I know?) Good job, Electronoobs!
Nice one. This part was needed for a project of mine. Thanks alot.
BTW whats up with the banana?
good project
Perfect idea. 😀
very very awesome
working
this is really helpful...... i tell you that!
Great tutorial!!!One question, what about the loads above 200 Watt, what changes do I need ???
Excelente video! Una consulta, sería posible utilizar software serial para la comunicación bluetooth? Quiero implementar un control de velocidad comunicado por RS485 sería muy útil poder usar el puerto serie para debug y software serial para la comunicación 485. Muchas gracias!
The current in Spain has 230V AC. That's why you have 227-229V on the osciloscope.
Yeah! It works, thanks
Hi! Good job, i have a question: talking about soft start, if i use an ssr driving it in pwm, do you think it works?
hello, nice video and explanation, is there a way to use micro / millis instead of microdelay? thanks
Who dislike this awesome video ??!!
Thanks for the video. I want to ask why have you added a delay after making the PIN3 HIGH.
Hi, great video! Thank you! Sample and useful! Great! But I want to ask you for range of voltage after the full bridge rectifier?
Or what is the max aloud voltage on input anode/cathode on EL187 optocopler?
Regards!
Great job, go ahead!!!
15watt 220v panel led dimmer adjustable circuit ....good idea .all people waiting
I'm planning to use this for speed control of a regular air fan. But I'm guessing I should use a snubber network to deal with the noise of the inductive load, right?
Excellent tutorial btw, keep it up!
well explained.....
Supper video i love it
Great Sir
my gosh, am in love
sir. please make a video tutorial about.. how i control my bed room light and speed control my fan
Hi nice job, what about solid state relè? Does it work with pwm for soft start?
Esperare el tutorial en español :)
HI ELECTRONOOB, nice work you had there. What can I substitute for GBJ1506?
When u connected the mains voltage to ur oscilloscope, u didnt connect the GND cable? Or did u had an isolation transformer?
Hi, nice video, I have a dummy question, how do you connect your oscilloscope, how can I see the the trigger pulse and the lamp wave?
I like the idea of using 817 opto coupler. Is it good to apply 220v at input of pc817 . I saw it in your schematic
Where do you connect the banana? Good job!
Hi. Thanks your videos. Once question. is it posible to control, adjust AC lamp dimmer or AC motor speed by potentiomter and NRF24? if yes. At Which can I be seen? Thanks
Why I always misspell your channel name😜 by the way you are great.
Serjeel Ranjan which letter are you misspelling?
You already know
Is it safe to connect dso directly to mains as the ground will b common for dso source and ac supply.??
Great.. 👍❤️
Can you upload how could you built the app on MIT app inventer
Please
Really nice tutorial..
And I have a question can u control more than one light bulb with this circui
I NEED TO DO THE SAME THING, AND I NEED THE CODE FOR THAT!!! IF YOU HAVE ANY IDEA????
maybe it's late for an answer, it is possible to control several lamps, the idea is to create a delay management with an array, the delays must be distributed according to a decreasing (or increasing) sequence.
Nice
VERY IMPORTANT SAFETY ADVICE!!
In english here! En español abajo!
Good circuit men I built something similar in the past. I need to clarify one point that is very important. Take care with inductive loads (motors, CFL...) especially with heavy ones!!, because triacs and also diacs have dv/dt specs, it means that if you change the voltage very fast the triac (or diac) can be damaged or even worse, destroyed :S. (When you switch ON/OFF a inductive load voltage spikes can happen). Also if you connect a heavy load (which demands a lot of current) there will be more power disipation on the triac/diac because Power = Voltage x Current, this means that the triac/diac can get very hot quicky and this will cause the destruction of the component. Check the datasheet of the component and put a good dissipator to prevent this ^^.
As bonus! ^^ To prevent problems with heavy inductive loads you should use a snubber circuit. Designing a snubber circuit requires more knowledge in electronics but if you are interested I invite you to search in google snnuber circuit for diacs/triacs ^^.
I hope you, people, understand my explanation :), I'm from Spain too :P. See you!! and have fun with safety electronics!! ;D.
EN ESPAÑOL!!! para los hispanohablantes! ;)
Buen circuito tío! construí algo similar en el pasado. Tengo que aclarar un punto muy importante cuidado con las cargas inductivas (motores, CFL...) especialmente con las "pesadas" (bobinas grandes tipo transformadores, motores grandes...) ya que los triacs, (tambien los diacs) poseen especificaciones dv/dt lo que significa que si se cambia el voltaje bruscamente (muy rápidamente) el triac/diac puede resultar dañado, o aun peor, destruido :S. (Cuando conectas/desconectas una carga inductiva se pueden producir estos cambios rápidos de voltaje de los que hablo). Ademas de esto, si se conecta una carga que demande mucha corriente (no tiene porque ser de tipo inductivo), habrá mas disipación de potencia ya que Potencia = Voltaje x Intensidad, lo que hará que el triac/diac se caliente muchísimo y esto puede causar su destrucción. Recomiendo mirar el datasheet, mirar que potencia soporta el componente, que intensidad y que voltaje ^^. También una buena idea es poner un buen disipador para prevenir estos incrementos de temperatura en el componente.
Como bonus!! ^^ Para prevenir problemas con cargas inductivas "pesadas" convendría usar un circuito llamado snubber, es como una especie de filtro que evita picos de voltaje, pero para diseñar uno hace falta tener conocimientos mas avanzados de electrónica, os invito a buscar en google snubber circuits for triacs/diacs (circuitos snubber para triacs/diacs).
Bueno después de todo este pedazo de comentario, espero que nadie se electrocute, se cargue la instalación eléctrica de su casa... jaja Disfrutad de la electrónica, si vais con cuidado nada malo pasara! un abrazo gente! ^^.
Para el Autor del vídeo! me identifico contigo yo también estudio ingeniería Electrónica y ya estoy casi acabando tengo 24 años! jaja Un abrazo sigue así y cuidado que no se te electrocuten los subscriptores! jaja :P
Hello Electronoobs, any procedure step for designing the app or any AIA code provided?
When you measure the AC Voltage on the bulb contacts, will it always be 220v but duty cycle will vary from 1-100%?
thank you so much. it worked perfectly.
which full wave bridge rectifier did you use?
@@bilalqasim2555 4 x 1n4007 diodes or 1 mb10m BR
@@mani5004 Actually I mistakenly bought a 2W04 bridge rectifier and its forward amps are 2.0 A. I connected it with my photocoupler and it goes bam. Can you give me any tip how should I reduce its amps to 0.5 mA? Thanks for replying btw
@@mani5004 If you have built the circuit and its working can you send it to me? If not then for zero cross which photo transistor did you use? and how many resistors you connect? because i tried the same circuit shown in the video and code its not working and my EL817 Phototransistor blow up. Any guidance?
@@bilalqasim2555 first check an ordinary LED with 4 1n4007 diode bridge rectifier in series with 100k 1/4 watt resistor. if it glows then connect it to the same EL817 optocopuler. it will work sure . follow rest of the diagram as in this vedio
Can i use it to control 1000W nichrome heating element?
one question:
Did you connect the photocoupler to 220v? All I see is 220v going to the full bridge rectifier and then the photocoupler? Reading it's datasheets, the photocoupler accepts around 5-6V? Am I missing something here? The schematic shows like that too, just 220V, no step down converters or such.. thanks in advance!
Can i use this method to control a 3kw heating element?
Hi bro first of all thank for this job .i want to do same think using three phase can you guide me.
I made this circuit and I am controlling brightness with a potentiometer. The dimming works, but I am getting visible flickering in my bulb. Could you please help me with that??
thanks!
Hello sir
Please help me
Can i use moc3052 instead of moc3051
And
Can i use EL814 instead of EL817
Please answer me
Can we connect celling fan without using extra protection circuit because coils are making negative voltage and it will damage the TRIC and DIAC
sir.
can i control speed of my AC ceiling fan by using that Schematic and code (Bluetooth) ?
Great video ! What's the banana for ?
Philip Gevaert for scale. Lol
wonderful work electronoobs,can you please tell me the name of Android application?
where the oscilloscope probe is connected so that it can be displayed on the screen? apakah di mosfet atau di output dimmer?
Hello, is it possible to buy something like that? I only need about 80W
if I want it to work as AUTO soft starter without variable resistance what would I change in the circuit?
Can we regulate ceiling fan via above mentioned circuit?
How are you probing AC mains without the big bad BOOM?!! Can you please explain.
Hi, I watched the video. I have a question, what value did you pass to arduino when you created the app?
Puede funcionar con un motor de los típicos de ventilacion para cuarto de baño.¿
Nice video. BTW you would not need a triac as the MOC3020 already has one :) It worked for me without the triac!
hello can you please tell me is it reliable to use triac for voltage controlling or is there any other method as someone told me when you control volatge with triac the current will increase very much
@@zuhaibchoudhary4635 Triac is one of the two options I know voltage controls, (the other is with mosfet / IGBT) and triac is very reliable. BTW In the MOC3020 it is recommended not to connect it directly to load
@arushgupta yes I know dear but Mosfet and IGBT are for controlling DC voltages I am asking for any other method than triac for AC control
@@zuhaibchoudhary4635 Oh, then I woyld reccomend triac cause that is the only one I know, do you know more?
No I also dont know anything elsw
could you help me.? i meet the problem with delaymicroseconds which it work only 2300 ms after zero crossing detection. thanks in advance
Is frequency gets changed by using triac. Also can I use a bridge rectifier instead of bulb for variable DC power supply. Can i use digispark attiny 85 instead of arduino uno(i don't need bluetooth)Please reply it
Thank you
Hi, I guess it's surely possible but just to be sure. Can we use the same schematic just switching the arduino with an esp8266 to make the dimmer wifi controlled ?
Hi, I designed the same circuit but I am getting only positive pulses at output, the negative half is completely clipped. Can you please guide what the issue is. The output of MOC3020 provides pulses in both positive and negative halves at the output but as soon as I connect those with gate of TRIAC, only positive pulses are there. What would be the reason (I already have replaced all the components).
kindly share its proteus simulation as well
Is it wise to connect ac voltage to breadboard ?
Shall I change any specification if my AC voltage change to 110V ?
(BTW the link of the full bridge rectifier is invalid)
Plz make video how to control with blyk and esp8266
Please tell me sir what I am using ic moc 3021 in the project plz tell me.
And what is the size of prototype pcb is it fixed size in 2$ price !
