Solved Help wiring 940nm LEDs for sensor bar

[Festiva]

So I am using 940nm leds(IR204-A to be specific) to make a custom Wii sensor bar. I am having troubles wiring them up and am hoping I can get some assistance.
So I know that I need a resistor with the led so that it doesn't burn out. I went here https://www.digikey.ca/en/resources/conversion-calculators/conversion-calculator-led-series-resistor entered in my values and it told me that I need a 1ohm resistor. So I bought these https://www.arrow.com/en/products/cf14jt1r00/stackpole-electronics to use with it. Im using a 5v 2a power supply as my power source.
This is a bad paint drawing of my wiring.

I think the issue is that the resistor is letting too much current/volts into the led killing it instantly. From reading the datasheet of the leds it seems that for 1A I can use 2.6v-4v to power it. Or for 100mA I can use 1.4v-1.8v.
My other question is can I use my phone's camera to check if the leds are powering up?
Any help is appreciated!

Based on a quick google, you can see that the LED requires a 190 ohm resistor in series with the power source. 1 ohm would kill your LED. NM is the wave length of the LED in nanometers.

I tried a 170ohm resistor and it brought the voltage down the about 1.1v, but the led still didn't light up when I looked at it with my phone's camera. Is there anything else I can try?

This is equation you use to find your R-limiting for an LED just plug in the values found on the data sheet where Vd is your bias voltage, Va is your initial Voltage and Vd is probably ground.

Test it by setting up the LEDs and waving a wiimote at them with a Wii powered on. It'll let you know if they're working.

I just tried turning off the lights and my phone picked up the leds and a Wiimote worked with them. Thanks for the help!
