Hi All,
I am new here (just registered) and know very little (almost nothing) about electronics, but i have a project on and seem to have opened a can of worms that has left me out of my depth!!
I have a need for a LED torch that has good throw to the beam, so have been advised to use an xr-e r2 cree emitter. Where i fall down is that i want it to be dimmable via a remote lead.
There are lots out there that are 3 mode, 5 mode etc, having varying preset brightnesses. What i would like to have is a dial that would take the brightness from 0% to 100%, with that dial being on the end of a remote wire (30cm long).
I am thinking of using 2xAA batteries, i know an 18650 would give better performance but i hear horror stories about discharge rates, temperature and explosions, so think 2xAA may be safer.
I thought that it would be just a matter of wiring an adjustable resistor inline, but i now know i was way off the mark!
Any help, guidance, advice or tips would be much appreciated, but remember to keep it simple as i am a novice.
Cheers, Tony
