AC dimmer explained| Design your own dimmer PCB for Arduino| Phase angle control using TRIAC

Dear Viewers,
In this video, we will learn the working of AC dimmer in details and check the simulation on Proteus software. We have used a bridge rectifier, optocouplers (MCT2e & MOC3021), Triac, and other components to execute this project.
Finally, an AC dimmer PCB is designed for you which can be downloaded following below mentioned link.

superb video! learned alot!! thank you TECHOOL Lab!

[lakmalichathurika]

Its help to improve my zerocrossing knowledge
Thank u🎉

[johnkunze]

Don't forget a snubber circuit for inductive loads. Got to do something with back feed current on stop....or pop!💕

[horizonfurnitures]

Thank you very much for sharing knowledge...Good luck for all your projects..!

[elmnaoirfer]

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

[arisudama]

thanks for the explanation. very helpful

[johnkunze]

The haa1 optocoupler needs no bridge only a resistor for crossover....cheaper and easier.❤️

[Funny_sto_rees]

sir what if i only connect live wire to dimmer and the gnd to the load
does it will work fine or not

[kenlin]

Please tell me, it appears in the opening video that you can use Blynk APP to control the AC Bulb with Arduino AC dimmer.😶

[jordanh]

Shouldn't that pull up resistor for the zero cross detector be between the optocoupler and the gpio?

[benetsonichulangula]

Sorry can you make this dimmer automatic, eliminating the use of potentiometer?

[alibingol]

Instead of optocuplor using to detect ZC. Diveder resistor can be used and tied to an analog pin to detect ZC

[parthpatel]

But we can use directly MOC3041 as zerocross IC 🤔

RBDdimer libarary pls, ı am not add to arduino

[dwinovianto]

can u share the RBDdimmer file? cz i cant find in my arduino library manager

[isnanhudayalubis]

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?

[NimanMan-dw]

Yg di jelaskan type berapa utk arduinonya, tks

[chiranjibpal]

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.

[dimasbagus]

Can this project work on an induction motor single phase?

[aitruong]

how do i calculate the number of resistors in the video
