Hi I'm working on a project that needs to identify the amount of people in a room. I'm doing that by using 2 break-beam IR sensors. I bought a DIY kit in maplin to see if it works. It was cheap and it seems it does. However, now I don't know how to connect ir to the Arduino! The assemble sheet and the product site will have to come in the next post since this is my first question here!!! Sorry!!! Any suggestions for how to connect it to the arduino? I actually only need a high/low signal!
