Awesome... This is useful... Thanks 👍

Welcome 😊

[@Roshni-aBrightnessinLife]

Very well explained 👏👏👍

[@hashincludeelectronics]

Thank you 🙂

[@MehulAcharya26]

Willnt there be any polarity issues??

[@hashincludeelectronics]

No 👍🏻👏🏻

What of if I want I use a 40W bulb and solar panel?

[@hashincludeelectronics]

That’s a nice idea . However I have not used solar panel yet . You can try and let us know 👍🏻

[@VirginiaZaki]

I do not understand how do we connect the AC plug does not automatically light up when plugged. how do I prevent it from doing that?

[@hashincludeelectronics]

Please check the video slowly and carefully for any missing step 👍🏻

[@abusufian2434]

Can we adjust(high,medium,low) the brightness of AC bulb automatically with the outside brightness??

[@hashincludeelectronics]

We can but not in this project . In that case you will need dimmer module . Also the LDR sensor should have the analog output .

[@abusufian2434]

@@hashincludeelectronics Can you please help me in anyway to make this project?? I am trying a lot to find a project like this but have not found any on internet.
i have found some where they use potentiometer. But that was not automatic.

hi, first thank you so much for sharing this tuturial, i have an issue with my light sensor, i'm trying to make it print if its HIGH then its the night, if LOW than its the morning but it keeps sending me 0 value
this is my code, can you please help me:
#define LDR 2
void setup() {
Serial.begin(9600);
pinMode(LDR,INPUT);
}
void loop() {
int mia=digitalRead(LDR);
Serial.println(mia);
delay(1000);
if (mia==HIGH){
Serial.println("NIGHT");
delay(1000);
}
else{
Serial.println("MORNING");
delay(1000);
}
}

[@hashincludeelectronics]

You need to calibrate the sensors sensitivity. Try changing the knob on sensor

@@hashincludeelectronics it worked sir thank you

[@hashincludeelectronics]

@@radiamoon2395 glad that it worked . Good job 👍🏻

[@biswanathghosh9975]

Good one❣

Do you live out ? of india? ?

[@hashincludeelectronics]

Currently yes.

[@chaylee4764]

can i have the codes on this project bro?

[@hashincludeelectronics]

Sure . It’s link is in the description.

[@alfegallardo8924]

Why need battery?

[@hashincludeelectronics]

It’s needed to provide power supply to Arduino. You can use ac dc adapter as well

[@sahugaming7432]

Plz give me code

[@hashincludeelectronics]

Code and diagram link is provided in the description of the video 👏🏻👍🏻
