Input

The library can use any of the digital input signals to receive the input from a 38KHz IR receiver module. It has been
tested with the Radio Shack 276-640 IR receiver and the Panasonic PNA4602. Simply wire power to pin 1, ground to pin 2, and the pin 3 output to an Arduino digital input pin, e.g. 11. These receivers provide a filtered and demodulated inverted logic level output; you can’t just use a photodiode or phototransistor. I have found these detectors have pretty good range and easily work across a room.

Output

For output, connect an IR LED and appropriate resistor to PWM output pin 3. Make sure the polarity of the LED is correct, or it won’t illuminate – the long lead is positive. I used a NTE 3027 LED (because that’s what was
handy) and 100 ohm resistor; the range is about 15 feet. For additional range, you can amplify the output with a transistor.

You can’t perform that action at this time.
