#4502 Hardware wiring for IR LED & Detector

Posted by James on 05 November 2010 - 08:50 PM

Could you post the schematic and part numbers? You probably cannot drive IR LED directly from Netduino pin, depending on its current requirement, which can be rather high (100 mA is not uncommon).

Here's a link for the schematics:

The IR Emitters use a 30kOhm resistor between the output pin and VSS. The IR Detectors use a 220 Ohm resistor.
