Thanks. Your hint to use 10 ohms for the resistor helped me get the emitter working for my IR remote control project. I was using 220 ohms and thought my LED was broken.
Took a few tries to get this right but rewatching your video got me there finally. Pay close attention to which side you place the resistor to act as a pull down on both the emitter and reciever.
Thank you for the clear explanation I really got it to work after watching several videos on the Internet. None of them was so clear like this one. Congratulations!!!
Oh my god. This tutorial should have been recommended earilier, cuz I just ordered 3 pin infrared receiver today! I wasted my money :( Thansk for amazing tutorial anyway.
Hi, thanks for the tutorial, it was really helpful I was wondering, would it be possible to connect the emitter to a digital pin instead of the 3.3v pin like you would with a normal led? thanks again.
I've been trying to create a remote for my lift tickets when I get out of my wheelchair and for some reason it will not send the IR signals to the TV or to the machine. My receiver receives the codes and stored them but for some reason the LED does not send. Do you ever have problems sending with these IR LEDs
Hello , im a student from the middle east, and i might need guidance for my project, is there any way i can contact you? Please do let me know thankyou
Hi, thanks for the video, I'm using a different photo diode and as soon as I hook up the earth to my pull down resistor it just goes straight to 0 and won't budge even when the led and diode are pointed directly at each other, I tried putting a 100k one in series with the 10k to make 110k and it still did the same thing, do you think I just need a much greater resistor for the pull down? It's been super hard to find good helpful info on these things for some reason :s
Hi Caleb thanks for your interesting tutorial. I have one question: I have one IR receiver but the specs are saying max 30V. Can you explain me what to buy as a receiver ? Maybe a link to this receiver so I can see the specs. Thanks for helping.
Hi the video was great and the first time I tried it the setup actually works and was showing values. But I tried to do it again and now its showing 0 values. Is there a way to troubleshoot this? I used the same material for the setup and its still zero.
If you're sure all of your connections are all the exact same, I would start by making sure none of your components are ruined. Perhaps either your emitter or receiver are burnt out. They get pretty hot sometimes and I've had some of them pop on me
@@calprowe I just need a wireless method for one arduino uno to tell another that it has detected something. For example, i have an arduino with a laser, and another with a photodetector. When the laser strikes the photodetector, I want the arduino to tell the laser arduino that it has detected the laser, probably by sending it a arbitrary message through IR. Do you think that I could use these IR leds for such an application?
@@aonoymousandy7467 it's possible, but these don't have much of a range and are affected by natural light and other things, so you might not get accurate readings. You could put the receiver on the laser arduino and the emitter on the photodetector arduino, when the photodetector senses the laser, it gives power to the emitter and gives a reading to the laser arduino's reciever. That's where I would start, just depends on how far away the arduinos are from eachother
Hello Caleb, that's a very nice video, this is exactly what I was looking for, I didn't have the same results due to the different IR LEDs that I used, but I have a question, the negative pin of the receiver is rated by 5V of Arduino, should the pull down 10k resistor get any voltage? Because the receiver gets almost 5V and 10k resistor almost nothing, I tried 5k and it continues the same voltage at the receiver.
I really appreciate this tutorial, it was really hard to find a good informative video on how to use these!
I know Im kinda off topic but do anybody know a good place to watch new movies online ?
@Uriel Aden i use flixzone. Just google for it :)
@Alijah Kohen yup, I've been watching on FlixZone for years myself =)
@Alijah Kohen Thanks, signed up and it seems like they got a lot of movies there =) I really appreciate it !!
@Uriel Aden You are welcome =)
bro Thanks. this is working perfectly. i tried to figure it out for like 6 hours and with you it was just 3 miuts.
Thanks. Your hint to use 10 ohms for the resistor helped me get the emitter working for my IR remote control project. I was using 220 ohms and thought my LED was broken.

Why does it look sooo easy? 🥺🥺🥺 thank you veeeeery much!
brooo thank youuuu, for real, I don't know why info about these components are kinda obscure

10 Ohm resistor for the IR Emitter at 3.3v of Arduino ??
Oh my god. This tutorial should have been recommended earilier, cuz I just ordered 3 pin infrared receiver today!
I wasted my money :(
Thansk for amazing tutorial anyway.
I use these for train detection and no one has good instructions for 940nm 2 pin LED IRs. Great job! Loved it!
Great vid. Exactly what I was having trouble finding and easy to follow.
is it possible to use a digital pin for the receiver and send a pwm from the led and read it on the receiver? bit like a tv remote would work!?
i think you actually don't need pinMode to read the analog Pins
thank you very much. I found zero tutorial on this before
great video, helped me a lot
Is it a photodiode or phototransistor?
Realy good.
Thanks man!
hey thx for the tuto ! does the number you get is the intensity of the ir led ?
Thank you, it helps a lot! I had to use a 100 kOhm resistor to get the values from 0-1023 range.
FYI if using older Nano ensure you select old bootloader in Arduino IDE as Processor if getting error when uploading sketch.
bro you saved my day i have an exhibition in 2 hrs n I was making the receiver connection wrong thank you soooooooooo much
Thank You for the great vid but you could give the code in the description
Hey, so. Question. Can we have two separate breadboards and separate circuits to point the emitter at the receiver from a distance?
thanks! thanks! thanks! I searched and search for this but couldn't find it. You are the legend!
Hi, thanks for the tutorial, it was really helpful
I was wondering, would it be possible to connect the emitter to a digital pin instead of the 3.3v pin like you would with a normal led?
thanks again.
you tried ?
Thanks mate..!! Liked and subscribed :) :)
in the title it says IF. Don't it has to be IR(InfraRed) ?
I've been trying to create a remote for my lift tickets when I get out of my wheelchair and for some reason it will not send the IR signals to the TV or to the machine. My receiver receives the codes and stored them but for some reason the LED does not send. Do you ever have problems sending with these IR LEDs
How far apart can you put these if facing each ither to make a trip beam?
Is there any way to make it work with temperature instead of distance?
Great video! Did anyone have idea how look scheme with two emiter and two reciever in row, just for covering more space?

Thanks bro
Thanks for the video. Do you need safety glasses to work with these? Also, would it be possible to connect 3 sets of these to the same arduino uno?
Yes it would be and wtf why safety glasses.
@@notmasterdelectronics Because it's a "Laser" ;)

Increase your pull down resistance...it will work
Thanks

Using 2 Pin IF Receivers/Emitters | Arduino Tutorial
I use 940nm Receivers / Emitters and the result is a maximum of 45
great tutorial. Is it possible to use the ir emitter and receiver as a method for wireless communication between 2 arduinos ?
Just depends on what you want to transfer between arduinos. What were you wanting to do? Just a proximity thing?

@@calprowe they are 30 feet apart
also one is outside and the other inside my house, they are separated by a window, could IR pass through glass?

The pull down is just to avoid inaccurate values between states (on or off), play with different resistors and see which works best
