Component that receives signals from a remote?

Hi, just starting to dabble in this and I was wondering if there was a component that can read the signal from a remote like this http://www.bhphotovideo.com/c/product/683524-REG/Canon_4524B001_RC_6_Wireless_Remote_Control.html

Essentially what I'm wondering if it's possible to use a remote like this to send a signal that gets read by the Arduino component and causes a signal in a computer, like turning on a light.

I've read some forum topics, and looked at some components in various online stores, but they all seem to work within a few inches, this remote would be at least 1m away, possibly more. I may be looking at the wrong things. What I want to do is use a program to give a visual countdown to the person that pushed the button that the photo will be taken. I'm pretty sure I can use 4V for the visual countdown part, but I need a way to get the signal into the computer to trigger it.

Thank you for reading!

You just need an IR-receiver. These are 3-pin components.


You will find one in a scrapped home appliance with remote control - e.g. an old TV, VCR, DVD-player, home stereo, you name it.

// Per.

You'd need a part like this

and will have to do some experimenting to find out frequency works best with your remote.

The Canon remote uses standard 36-38 KHz modulation like standard TV-remotes.

Wow! So small, I was looking at the wrong thing after all. And it looks like with the right amount of experimentation, this is possible! Awesome, thanks!

EDIT: updated for modulation frequency

Here are some signals I just captured for a canon remote

There are 2 diffent types in the signal:

S & 2S (the RAW signals) Modulation Frequency: 33.5 kHz (use 33kHz with IRremot or IRLib)

A, W T (The NEC signals) Modulation Frequency: 38 kHz

May work for your device....
