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!
