(updated) [I noticed the link was wrong…]
I want to make a IR detector so that when someone crosses the stream of light I get notified in my audrino and my audrino turns on some LEDs (similar to this project http://alan-parekh.vstore.ca/product_info.php/cPath/1_2/products_id/1) . I am a newbie on all of this electronic stuff so half of the time I am not entierly sure what I am doing… any help is appreciaited.
With this project in mind I went and bough the stuff that they listed at the project website. When I asked for the IR detector the guy asked me if any kind of IR detectorand I said yes, because I didn’t have the specifications.
— Here comes my question— >
Recenetly I learned that a IR detector and and a IR Reciver are not the same. Okay so I have an IR detector, I think… The vast majority of the IR detector that I see out there have 3 leads(wires?) to connect them. Mine only has 2, and it kind of looks like this one in here http://www.hobbyengineering.com/H1217.html …I am assuming the IR detector that I got is this one… but who knows…, this things don’t come with brand markings so is hard to tell… okay so if this is my IR detector (or a similar)…
how do i connect this thing…? and detect the signal being passed.
At the project website I noticed that they connected positive wire to a 47Kohm resistor, that is connected to the positive lead of the to the IRDetector, they then connected a yellow cable on the same lead after the resistance (which I assume goes to the IC). Finally they connected teh negative side of the IRDectetor to the negative cable. I thought I tried that on my breadboard… but now that I look at it again… I might have not… so I will try that tonight… but any help you can provide PLEASE PLEASE let me know.
Here are some pictures of the IRDetector…(or at least that is what I think it is) HELP!!!
