Using 2 Pin IF Receivers/Emitters | Arduino Tutorial

Here is a simple sketch that allows the user to get a range of values using a two pin infrared receiver and emitter.

I really appreciate this tutorial, it was really hard to find a good informative video on how to use these!

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!!!

I use these for train detection and no one has good instructions for 940nm 2 pin LED IRs. Great job! Loved it!

brooo thank youuuu, for real, I don't know why info about these components are kinda obscure

[kaypoland]

thanks! thanks! thanks! I searched and search for this but couldn't find it. You are the legend!

[ElGalloUltimo]

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.

bro you saved my day i have an exhibition in 2 hrs n I was making the receiver connection wrong thank you much

[ciemniaa]

bro Thanks. this is working perfectly. i tried to figure it out for like 6 hours and with you it was just 3 miuts.

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, it helps a lot! I had to use a 100 kOhm resistor to get the values from 0-1023 range.

[DerekNoon]

Great vid. Exactly what I was having trouble finding and easy to follow.

[electrotsmishar]

thank you very much. I found zero tutorial on this before

[kari]

Why does it look sooo easy? 🥺🥺🥺 thank you much!

[billysbikes]

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!?

[akhaqan]

Thanks for doing this, not much info available on this. Any idea what values would we get without the pull down resistor?

[kangsankim]

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.

FYI if using older Nano ensure you select old bootloader in Arduino IDE as Processor if getting error when uploading sketch.

10 Ohm resistor for the IR Emitter at 3.3v of Arduino ??

[maalonszuman]

hey thx for the tuto ! does the number you get is the intensity of the ir led ?

[rmecha]

thank you! i dont need to rely on the three pin IR obstacle module
