I'm working on a project that powers 6 LEDs, all 10mm super bright (.5 watts) red.
I'm powering them with a single 18650 LiOn battery (3.7 volts).
The LEDs are each separated by about 6 inches of wire.
A few questions:
- ideally I'd like for the LEDs to be dimmable. I know this should be done with PWM, but given the low voltage (and a desire for simplicity) can I just increase the resistor value?
- and would it be possible to use a variable resistor to get variable dimming?
- and can I use a single resistor (variable or not) for all the LEDs (assuming they're all identical)?
- I'll be daisy chaining the LEDs together. So 2 wires will connect to each LED. Is there a neater way to connect the wire to them than soldering?
Thanks for any help.
