These look interesting for using with an Arduino - please does anyone have an idea as to how to wire them up?

I've just ordered a pair and will be trying to use them with my arduino, I'll let you know what I figure out. If you understand all that technical mumbo jumbo you could check the document that is linked to in the listing, which is the datasheet.

This photo set shows an application that works. I got this running last night.

What RyanM said worked for me too, but I used a 10 k ohm resistor instead of the 5.6 k.

Was thinking about using these for an arduino segway. What kind of range do these things have?

Using RyanM's schematic (I didn't have a 5.6k so used 6.2k instead), I found it has a range of 0 to 2cm however it's most accurate between .5 and 1cm.

By most accurate I mean that the Analog in range varies a lot. At 2cm, you are up to 950-980 (~1018 is the value when nothing is in front of it).

I'm thinking of using these to detect Kub Cars on a Kub Car track.

Will these be able to detect the cars even if painted dark colours?

I plan to out them on the under side of the track and the cars pass over them with a gap .93cm. That may be too far away.

It's hard for it to detect black, in my testing it starts detecting black at about 1cm. But as always you should test it out yourself.

I've done some more testing and it can detect up to 3cm if you are lucky.

Any chance of a future breakout board for an array of five of these? This would be a no-brainer for a line following bot.

I am currently making one from grid PCB and its a little tedious with the 10 resistors, 5 capacitors, power/ gnd rails, and signal pins brought to a 1x7 female header. I will have to design a breakout PCB if I end up making many of these.

I made a demo how you can use these to build an array for line following. The array demo can be found at http://www.youtube.com/watch?v=SVdbP_Plils

These are used as digital inputs to an AVR microcontroller (no ADC required). The detector swings from about 150mV to Vcc - 150mV. The detector circuit I used has a 10k resistor in parallel with a 0.1uF capacitor at the collector of the IR detector (output voltage is at the collector). Works very well as long as the sensors are close to the surface used.

Does anyone know what the response time for these are? It wasnt clear to me from the data sheet.

Rise time 10uS, fall time 50uS. So pretty darn fast.
