infrared extending IR range

Posted on Feb 6, 2014

Using this schematic I doubled the range of my IR LED, the power drawn in the circuit is now 37mA. My former circuit, without using a NPN transistor drew 20mA (JeeNode max per digital pin). So that`s almost twice the power. You could increase this even further using smaller valued resistors, but that would push the boundaries of the LED and transi

stor. I didn`t need any bigger range anyway as I use IR emitter cables attached to my devices.
