Hi, i m quite puzzled with the https://www.adafruit.com/products/2349 kit
usuallay, adafruit documentation is fully usable, here, there is NOTHING
I have one simple question, how to cable it to the arduino ?
I have found some information about similar products: http://www.spikenzielabs.com/Catalog/in ... cts_id=967
but this is not sorting any valuable result
thanks

Re: how to cable IR sensor on off ?
The circuit from the Spikenzielabs link should work. It is a very similar device.
Wire the 470 ohm resistor in series with the LED side (the left side in the photo). Use the 10K as a pullup for the collector on the phototransistor side.

hi bill
hum this is not working.
i m supposed to receive levels on analog or digital ?
inner pins are groudn, right ?
could you provide a schema of wiring ?

Re: how to cable IR sensor on off ?
You can use it as either an analog or digital input. The analog input will not be very linear, so it is not a precision rangefinder. But it will give you an idea of how close the object is.
The center pins should be ground. Post a photo of your wiring and we'll take a look.

Here it is !
i want to use them just as on off, no distance precise measurement

You have both grounds connected through the resistor. The phototransistor side should connect direct to ground.

ah yes ! left - right ad upper michmach
thanks a lot.
here is the diagram correct, but it would be really nice you add it in the page of the product

Re: how to cable IR sensor on off ?
yep, please, i think we are a lot to buy adafruit for the aspect: wiring + code + library aside the product
