LED 6100 - resistor?
« on: September 05, 2015, 03:14:01 AM »
I thought I read somewhere that the TSAL 6100 didn't need a resistor but is this because the MilesTag board has one already?

I'm experimenting with an arduino board and I don't want to destroy my IR leds.

Once I have some confidence that I can get the system to work I might then start to understand what the hell I'm doing...

In at the deep end.

Did you answer your own question?

My experience with the tsal6100:

if your system runs on 5V and you put no resistor in series you blow up the ir led, it actually popped when someone made that mistake

I usually have 2 to 3 Ohms in series with it, but had success with a 1 Ohm resistor in series as well. Mind you: my 1 Ohm resistor was placed on a small separate board so I could swap out resistors easily, so due to contact resistance the total resistance would be more than just the 1 Ohm.

Cheers,
