resistance more than 10k.
10k is too hign. Usually leds take 20 mA, may be more in impulse mode,
so base on Ohm law resistor should be:
5 V (power or digital pin) - 2 V (cross diode) / 20 mA = 150 Ohm.
LMRAO, I just realized that I was using 220"k"Ohm resistors I thought were 220 Ohm resistors. At least my math was correct on what I needed in there, even if my implementation was just a bit off.....! On the plus side I got around 50 feet using the 10 Ohm. Glad I only had time to pulse it twice very quickly,
Thanks for the quick replies.
