Hello everyone,
I’m trying to create a single LED powered by a CR123A battery with a brightness control knob. I’m a noob and I’m learning a lot about this, so please don’t roast me too hard.
I understand that a CR123A is 3V, so that would blow the LED outright.
Do I need to find a dimmer that controls voltage and adds resistance? Ideally I’d like the switch to click on at the LED’s V_min and not go beyond the manufacturer’s recommended ~40mA range.
would this be easier using a AA battery and something that boosts voltage?
I saw some LED dimmers online, but they plug into a LED driver (dunno what that is) and seem to control devices in the 12V range or RC car knobs that still go all the way up to like 8V. Can you customize a voltage knob?
thanks, any help is appreciated and I’m willing to learn
