5v Relay Trigger circuit 8 channel Relay driver circuit with ULN2803 in Hindi

In this video I will show you how to make a optically isolated 8 channel 5 volt relay module by using minimum electronic components, I would make a low cost relay module which will be efficient as ready made relay modules available in market.
Watch this video till the end, in next part of this video I will make this relay module to be controlled by Arduino.
______________________________________________________________________________
Required components:
1. 5 Volt Relay x 8
2. PC817 IC (Optocoupler IC) x 8
3. LED (any colour) x 8
4. Resistors 220 Ohm x 8
5. PCB

Great video bro mjhy boht help hoyi

[@StreuB1]

I don't even speak or understand Hindi and I was able to follow along with this. Well done.

I know I'm kind of randomly asking but do anybody know a good website to stream new tv shows online ?

Sir maine low trigerd wale circut ke compont mangva liye kya wo kaam nahi karega kya

[@user-of7st6vx9v]

do you check the output uln2803 because i checked it and i found 3.5volt i don't understand why

[@basitraza7991]

12v ke bjay 5v ke relay or 5v ke battery b use kar sakty hain?

[@song-tg6ds]

Sir plz sabhi vedios ko translet karo

[@lambert8443]

I have an essential question, once we use ULN2803, can we do without the free-running diode for the relay?
thank.

[@jobaptist]

yes, you can

[@starunique42]

2 video????

[@fasihzafar7423]

Bhai kya is relay m diode use karna jaruri hai ya nai ????

[@DebajyotisLab]

Agar aap transistor se relay drive kar rahe ho tab freewheeling diode jaruri hota hai. Relay driver IC pe already freewheeling diode rehta hai, to yaha pe jaruri nahi hota hai.

[@devsong8587]

Maine 10000 ka meteraiyal kharid liya abhi ban nahi raha plz help me

[@fasihzafar7423]

Kya problem aa rahi hai appko.... Details m bataye ????
