Sorry to be off topic but does any of you know a method to get back into an Instagram account?
I was dumb forgot my password. I love any tips you can offer me.
@Chris Jude Instablaster ;)
@Edison Anthony i really appreciate your reply. I found the site through google and I'm in the hacking process atm.
Seems to take a while so I will reply here later when my account password hopefully is recovered.
@Edison Anthony it worked and I now got access to my account again. Im so happy:D
Thank you so much you saved my account !
@Chris Jude happy to help :D
For those like me who have had trouble making this work, this might be because your LDR is calibrated differently from the one in the video. To fix this issue, try replacing the "300" with other values until it works.
had to adjust my ldr status to
I've been doing a project in design school that needs this exact circuit and I haven't been able to figure it out! Thank you so much!!
The instructions and steps are organized and clear.
The video quality is perfect.
Thanks very much for sharing your knowledge with us.
Muito show... Explicou em 4 minutos um conteúdo grande com riqueza de detalhes...
O Brasil estaria em outro nível se a maioria dos professores tivessem esse dom na didática.
You are my hero, i can sleep this night, ty bro
You can now sleep you dont have an led shining in ur eye
The best ldr tutorial that will ever be
clear guide on writing code. Comments in code section helped a lot.
The code is so simple. That is help me to understand how it work!
Would you mind explaining why we have to use 10k ohm resister with the LDR.
Thanks mate, really helpful
this video was really helpful!!!!
thank you, thats the solution for my projeckt
nice video. thanks for the tutorial
Good tutorial and I find this music very enjoyable :-)
thanks for this it worked like a charm
Thank you for sharing ;0) i got it working. I ❤ you.
Thank you very much for this project. Could you put a video that when the ldr does not detect light, and the sound detection detects sound, then the led lights up. But if the ldr detects light,
and the sound detection sensor detects sound, then the led does not light up.
Its a great and helpful tutorial, thank you! but what if I want to add 13 more 4.5 lumens of LEDs to the construction to make it brighter? Do you mind helping me how the construction is going to be like? For eg. how many more resistors do I need to add and what are the values for each resistor? Your help and response would be more appreciated!
How can i combine this with a button? i already have an if function but when the button is pressed then the ldr does not work... thanks
Realy I love your video's.
Hi, why do we need the 10k resistor?
Creative video, thanks for sharing :)
Great video, if your light sensor is still not working. Try changing your ‘ if ‘ statement. As 300 is working here it doesn’t always work for everyone. Mine was 5
is there any diffrence btw programming an arduino uno & Leronardo !cuz i wanna try the same thing but with the leanardo arduino ! & why do we need an arduino to do this in the first place .. ?
Hi, is it possible to dim an RBG LED with a photoresistor on Arduino?
thanks
Ithınk You are the best youtuber
What do I add to the code if I want it to blink while not being covered?
I followed your exact sketch and cross checked the connections. I can't find out the problem. When I check the serial monitor, all I see are senseless symbols. Please help
you are awesome.can you connect the led strip with this method?
Does it also works if I use an Arduino Leonardo instead of Arduino UNO?
hello, i have a question regarding the resistance value.
why 10kohm and 220ohm is chosen instead of others value?
is there a reason for these? if yes, are they any formula to prove so?
looking forward for your reply.
Ohm's law. The resistor for the led controls the current and is there to kerp the led operating within it's operational parameters.
it's the best video thank you so much
Hi. What if I attach about 8 LEDs? I don't know how to program it anymore. Can you help me with it?
Helped me in my college engineering course!!! Thank you
this is the right way to make LDR photoresistors.
Can anyone tell my why there has to be a resistor after the photoresistor and the wire to ground? Cant the power just go into analog in?
Awesome, it worked!!!
If i could understand what I'm writing down, that would be awesome. :D
I have an ldr sensor board, can I still do this?
Why did you choose 300 for working rate of LDR?
Tell some info about the working principle on Arduino codes?
why did you plug a cable in A0 pin?
Say sth. about the LDR and Resistor section over board.
Selam hocam elinize sağlık çok güzel ancak birde bunun tersini yapmanız mümkünmü aceba işıgi görünce yanacak karanlıkta sönecek
Question: I noticed the rate at which the serial port was displaying the output was pretty quick. Can this rate of reading the LDR values be increased with a higher baud rate?
I don't think so. But why would you want it to display quicker than that? The reading doesn't need to be any where near that fast for a working project anyway.
I will be building this to control the lights around my building every day, and it will read the light levels just once per minute, and only turn the lights on if the light level has been below the threshold for the last five or ten minutes. Likewise with turning the lights off.
how can I do to turn on more led's?
any one can answer me? may LED still working even though its not dark
LDRStatus is the voltage or resistance of LDR?? kindly help me
will it explode if a use 330 r instead?
I have copied the whole program carefully but contunuesley error is coming that 'AO was not decleared in this scope' please reply me out and help me
Hocam ben şerit led i naısl bu sistemde kullanabilirim
Which video making software do you use
how to fade rgb led with ldr not on and off just fade?
can it work with switch case
My LDR status just keeps returning 0. Would be from my wiring?
THANKS A LOT
thanks so much dude
а як зробити коли світло - показує зеленим, а коли темно - червоним?
And to use 2 LEDs? Each one with its sensor? How would the scheme look? Thank you very much in advance!
And to turn off LED when it's dark and turn on when have light, what i need to do?
Thanks!
1:27 the resistor is between the lrd and the wires and in 3:58 the resistor is after the ldr. Why?
why we use 10k resistor on ldr?
Sir I am big fan of all of your projects kindly make GPS land leveling with arduino...
Hi. I just found about this amazing video po of yours. Can I ask po why is it 300? The reason I ask is, the first time I run the program using ldr, the monitor prints.. 1023.. what is the difference between putting 300 and 1023 in the condition? sorry for the disturbance sir.
its work ! Thanks
çok başarılı ve açıklayıcı
BEST VIDEO👍👍👍
Could you please make a video of how to make the LED turn on when there is light and turn it off when the LDR detects darkness?
Lol switch the of statement
Please give circuit diagram
thanks!
Can we put 100 k resister
Please provide schematic in Fritzing, it would be so nice.
why my led is always on even it its not dark? answer m pls
wilbert ortilla try changing from 300 to 100.Mine worked.
increase the analog Voltage in code. it is
Otg
@@tryhardsomethingelse2658 mine is not glowing darker even i changed 300 to 100
can you upload the programing
Thanx Thanx a lot.
Nice video sir
thanks for that
what is LDR
We tried and the LED did not light up but gave the line Serial.println. Then I changed the ldr status to 1023 and the LED stayed on. Any thoughts as to why?
Same question of serial.println
Thanks it's work
bro u hve very cool videos suoerb videos just make yourself audible to make it extra cool
It worked!!!
For this how to connect PIR sensor
Tienes la simulación en proteus, o la placas?
thanks
Good job bro, thank you so much for thi tutorial
Can we use 470 and 1k ohm resistors instead of the ones mentioned
Yea sure why not
I'm new to arduino. Does analogRead(ldrPin) read the voltage or the current?
analog pins divide 5 into 1024. and according to the input voltage ,it shows you some results(numbers).
Could You add schematic of connections.
Followed the same steps, but led is always on even when I've focused a torch to the ldr. Please help Mert
Same happened to me.maybe your code has a fault."
good video be blessed
thank you
did anyone tried to combine this with solar tracker?
How to upload these values on webserver or webpage automatically every 15 or 30 seconds??
Superb bro,works pretty well.
Can we use 470 ohm and 1k ohm resistor instead of the ones mentioned??
uh, I think i made something wrong but, I have no idea what it is. Pls help (I'm trying to control two LEDs at the same time)
//set pin numbers
//constant won't change
const int ledPin = 13;//the number of the LED pin
const int ledPin_2 = 10; // the number of the second LED pin
const int ldrPin = A0; //the number of the LDR pin
void setup () {
Serial.begin (9600);
pinMode (ledpin, OUTPUT); //initialize the LED pin as an output
pinMode (ledPin_2, OUTPUT); //initialize the second LED as an output
pinMode (ldrpin, INPUT); //initialize the LDR pin as an input
}
void loop (){
int ldrStatus = analogRead (ldrPin); //read the status of the LDR value
//check if the LDR status is
in my case it is on all time help
really super
you are so good
My led got very dim ...plz help
Thxx
Sir can we light 2 LEDs?
If yes then the connection should be series or parallel?
Mine worked in parallel
you are BACÁN! thanks!
