LEDs (Infrared)

IR LED 850 nm (Reel)

IR LED (5mm, 850 nm, 30˚)

These LEDs are very useful for IR illumination and for creating IR beacons that you could track with the PS3 cameras.

You can NOT run these straight with the Arduino digital output pins, because they need 60 mA of current to operate. The Arduino digital output pins can only provide 40 mA. You will need a transistor to control these LEDs with an Arduino.

Use the Ledcalculator to calculate the resistor values you need.

IR LED (8mm, 850 nm, 3-chip, 60˚)

The longer led of the LED is the anode (positive).

These are very powerful IR LEDs. The 8mm ones are more powerful and have a wider angle than the 5mm LEDs. They very useful for IR illumination and for creating IR beacons that you could track with the PS3 cameras.

You can NOT run these straight with the Arduino digital output pins, because they need 140 mA of current to operate. The Arduino digital output pins can only provide 40 mA. You will need a transistor to control these LEDs with an Arduino.

Use the Ledcalculator to calculate the resistor values you need.
