Pin out on your PC817 is wrong. This is 4 PIN device. SCR = Silicon Controlled RECTIFIER! (not resistor) I gave up at 8min as it seemed I already knew more about this subject than the material presented in this video. Sorry...
@@CETech4u OK thank you sir Can you please help me to draw circuit diagram of MOC3021 to TRIGER relay Application : I want to control relay with the help of MOC3021 and MOTOR ON and OFF MOTOR with the help of relay as output. I also draw circuit diagram but not work well ronakprathod@gmail.com
Hi I tried with 4N35 and connected to AC with 330K Resister in between and given 5v on other side to check the AC main detectation but didn't work. i want to build AC mains detector so I can check on microcontroller can I use the above circuit shown at th-cam.com/video/OIkQ6evY-mg/w-d-xo.html
16:40 There is no UN35 opto coupler, it doesn't exist, you can't read your own handwriting. 4N35 and it's a photo transistor, not a photo triac
Good, now I can use it to trigger 12v relay with out worry about its lifetime .

can it be used to make ethernet surge protector?
Sir. What type of photocoupler 817A.it use dc or ac? Is it same with PC817...

Hello sir I want tell you one thing can we use MOC3021 TO TRIGER raley instead of the PC817
Yes
@@CETech4u OK thank you sir

The dimming works only for the traditional aka Incandesent bulb not for CFL or LED bulbs
who use the Incandesent bulb ?/
What is the maximum current input (across anode and cathode) PC817 can take?
How to use dc switching like switching a small nichrome wire filament ?
What is the function of pin number 6 in PC817
Could you explain the letter back of PC817 suffix, likes MOC3021 ? Thanks
Please provide how to test PC410l AND pc457l opic Photocoupler
Sotrry 4N35 is transistor type NOT Triac Type
16:42 “this is our curse signing off.”
Hey, how can I detect AC using it?
I am not aware of any such application of the OC/OI. Do share with us if you find something related to this
CETech I found something, actually you need to add some current limiting resistance and a cap and it can detect it!
Seems interesting. Will look at it.

Hi
I tried with 4N35 and connected to AC with 330K Resister in between and given 5v on other side to check the AC main detectation but didn't work.
i want to build AC mains detector so I can check on microcontroller
can I use the above circuit shown at th-cam.com/video/OIkQ6evY-mg/w-d-xo.html
There is no UN35 opto coupler as in the video, it doesn't exist, 4N35 is a photo transistor, not a photo triac which is why it didn't work for you.
