Hello all,
First, sry for my english, im french ;)( plz correct me ;))
I want to create an IR Pen and an IR array.
 - I see that the TSAL6400 is the best for IR Pen. I want to know, if the TSAL6400 (50°/1.5V) is the best for array ? Or if a led with a greater angle will not be better ?
 - I want to know if somebody already has tryed a 950nm LED (like : TSUS5400 (44°) or TSUS5202 (30°) at 1.3V , or maybe at 1.6V TSAL5300 (44°) or TSAL6100 (20°) ?

Other question if i put a TSAL6400 on a 1.5V battery(AAA), do i must use a resistor ?

Thanks for all !
AnX

Depends on how you are using the IR-Array. If the Wiimote will be detecting IR direct from the array (Wiimote faces IR-Leds) then yes TSAL6400 is your beast. If you are tracking a reflection then unknow.

I TSAL6400 or TSAL5300 on a AAA won't need a resistor (id does need a very small one but won't make any noticable difference.
