Hi everyone,
I just have a question about if my current limiting resistor value. I am totally new at this, and I am sorry if I am asking a stupid questions or doing something wrong. I am planning an using a Li-Ion 13500 3.7V 1400mAh PCB Protected Rechargeable Battery Module and a green Luxeon Rebel Star which I think has a diode forward voltage of 3.4. I believe the LED is running at 1000mA. I put the numbers into a LED calculator and it gave me a 1ohm 2w resistor. Are my numbers correct? I also planning on getting a Nano Biscotte Sound Module V3. Will I need to add any numbers in my calculation to account for the soundboard? Is there anything I need to know for ordering everything?
