I really like the use of a transformer to secure the current of the optokopplers diode. However I dislike the uses of blocking funktions like delays or serial.write in a interrupt service routine. I recommend to seta flag in the ISR and to handle this in the main loop

Great video! I made the same using PIC microcontroller. But nowadays, it is no longer very practical because resistive load bulbs are no longer used. I'm currently using "Dimmable LED dichroic" with this circuit, but it is not the same! Low dimerization doesn't come down so elegant, even doesn't came to zero effectively.

For what are you using the Zero Crossing Detector? Is it for turning syncronizing the Arduino, so that the Demo Circuit gets turned on when the AC voltage crosses zero? And if so why don't you make use of it in your code?

Thanks for making such a great video on my request. 😍😍 I will implement the same ckt in my next project.

Hey, I saw you using MOC3021 which is a zero-cross triac driver. Isn't a random phase triac driver suitable for phase angle control?
@drdream1233 жыл бұрын
Would this work to detect the phase angle of incoming AC so convert existing dimmer to PWM?

Sir, what is the rating of potentiometer?

And what about iot based ac dimmer using some android app like blynk. Something like dimming ac loads via android app instead of potentiometer.

Can I use it for 3 phase motor??
@hussain550194 жыл бұрын
You then have to use it for every phase its better to use VFD instead of this because by this method the motor may gets damaged due to high current at low voltages..
@dieSpinnt4 жыл бұрын
You have to take in mind that the zero crossing point is where the steepest current flow in a sinusoidal curve occurs. So maybe this isn't what you want when inductive loads like motors are involved. Calculations first:)

Can I use moc3023 insted moc3021 and what i need to change if I can do it with moc3023
@me163bkomet4 жыл бұрын
Yes, you can use the MOC3023 and you don't need to change anything in the circuit. The only difference between the 21, 22 and 23, is the current needed through the input LED to ensure the latching of the TRIAC output, beeing the 3023 the ones that needs less current to do that, and if the circuit is designed for the 3021, and it works well, surely it will works with the 3023

it's a simple straightforward project. you need to be careful while doing the connections. Follow each and every step.
@ElectroniClinic5 жыл бұрын
first of all, make the zero crossing detector circuit and check if you can read the frequency. then start working on the dimming portion.
