Can I use other pins to enter the signal to the controller other than pin 3 and 2 in the same program, because I want to cut 3 phases for an induction motor
Can you please anybody help me in searching for a device/circuit for some special work. Actually, I need a device that would gradually increase (for 2 hours) the voltage upto peak and then would gradually decrease (for 2 hours) the voltage up to dim/off. The device needs to be connected with four 15 watt/25-watt warm white bulbs.
Its help to improve my zerocrossing knowledge
Thank u🎉
Don't forget a snubber circuit for inductive loads. Got to do something with back feed current on stop....or pop!💕
superb video! learned alot!! thank you TECHOOL Lab!
Thank you very much for sharing knowledge...Good luck for all your projects..!
We appreciate it. Thanks a lot!

Thank you, excellent video!
We appreciate it, Thanks
Great proyect, good explanation!
I appreciate it. Thank you!
The haa1 optocoupler needs no bridge only a resistor for crossover....cheaper and easier.❤️
Great stuff...
Great explanation Thanks
Instead of optocuplor using to detect ZC. Diveder resistor can be used and tied to an analog pin to detect ZC
Nice explanation, thanks a bunch Sir
thanks for the explanation. very helpful
Thanks brother for your kind words. We will try our best in future videos too.
Please tell me, it appears in the opening video that you can use Blynk APP to control the AC Bulb with Arduino AC dimmer.😶
sir what if i only connect live wire to dimmer and the gnd to the load
does it will work fine or not
Sorry can you make this dimmer automatic, eliminating the use of potentiometer?
Shouldn't that pull up resistor for the zero cross detector be between the optocoupler and the gpio?
No Mr Jordan, because optocoupler is further turning internal transistor.
And the transistor is grounding 5v through 10k resistor to ground
Thanks! It looked I was looking at the transistor backwards I guess
Thanks for watching our video!

RBDdimer libarary pls , ı am not add to arduino
can u share the RBDdimmer file? cz i cant find in my arduino library manager
Sir can you provide library link
But we can use directly MOC3041 as zerocross IC 🤔
this would be good to switch the AC on and off but if you want to create a dimmer you need MOC without the ZC. Otherwise it will not work.
@@Mikomanus thanks 😊
Thank You
Please explain for 248 262 volts
Yg di jelaskan type berapa utk arduinonya,tks
I connected arduino out pin to MOC 3021. But the MOC not operated. The voltage of arduino pin drop to 1 volt. How to solve this?
there is a missing resistor to limit the current to MOC buildin led. Put a 200-300 Ohm resistor between pin 9 of arduino and Anode pin 1 on MOC
how do i calculate the number of resistors in the video
Could you add BOM and P&P file please?
how can I open the programming part on Arduino plz.
Please watch our video on dimmer with Arduino

Can this project work on an induction motor single phase?
It will not work for motor.
@@techoollab8360 What components are needed in order to work for motor?
For ac motor we need variable frequency drive

Mr @Chiranjib Pal , if it's filament bulb then it can be easily designed using dimmer.
@@techoollab8360 Yes. It is the filament bulb. I need a self-programmed automatic dimming. Not a man-operated regulator/ dimmer. Please help/ suggest
Yes, it will work. All details related to components and program is there in this video. If still you need any support you can contact us.
It doesn’t work
Você poderia fornecer o código-fonte do arquivo?
There is too much flickering , i am using the circuit with nodemcu
Downgrade your board to 2.5.0 from Arduino board manager
can it be for 3 phase motor?
This circuit will not work for three phase motor
Even not work properly for single phase motor
