How to use Optocoupler and Triac to control AC Load (Tutorial :80 in हिंदी)

[@anilkohli9564]

Praveen ji apka cuircut ko samjhane ka tarika bahut hi achcha hai bahut bahut dhanyawad Aapka.

[@nassiri1355]

Man, I didn't understand 80% of what you are saying. But somehow you help me reverse ingeneering my garage door opener, I tought the TRIAC was used to slow down the motors but I couldn't find zero cross detection circuit, now Its Clearly been used as a switch. Thank you. Great work.

[@MrCBINO]

hi praveen, as usual you've upload a very useful video. thanks for that. I've a small doubt over this. it's cleared that that the triac can handle the maximum output load by it's part number (ex) BT 136,7,8,9......but i need to know whether the voltage across the triac is same as the input AC voltage. for ex: if the input voltage is 230 from the direct main, & will it be the same voltage value after it converted through the triac which is present inside the IC (opto coupler) ? please clear this doubt and also add some more technical videos to learn. actually I'm learning lots of things from your uploads. I'm eagerly waiting for your future videos. once again thank you. god bless you

[@jotirlingswami9357]

Hi I Like your Videos I want to build the AC dimmer as AC ON-OFF switch Can I use the same circuit with the ESP8266 Node MCU ]WIth ESP8266 Node MCU to enable PWM on a certain pin, use analogWrite(pin, value); where the pin is the digital pin, and value a number between 0 and 1023] Use case : 1. When I set 0 value to the digital pin by analogWrite bulb should turn OFF. 2. When I set 512 value to the digital pin by analogWrite bulb should set to brightness 50%. 3. When I set 1023 value to the digital pin by analogWrite bulb should set to brightness 100%. I have a doubt : Arduino NANO gives an output voltage of 5Volt but ESP8266 nodeMCU gives 3.3 Volt. will this works please replay to me I am learning a lot from your Videos. Part : MOC3021 and BT136

[@chrisanderson4887]

Thanks for uploading. I want to control DC, so will the circuit work if I simply swap the Triac for a Mosfet?

[@surajsurya1928]

For controlling ac devices use triac and for dc devices use mosfet.

[@surajsurya1928]

For controlling AC devices use triac and for Dc devices use Mosfet.yes, of course it will work if you swap the triac and replace it with a mosfet provided you should select the mosfet/triac according to current drawn by the device your are going to control and always use a heat sink for both high current or low current applications.
