Hi all
I have a string of led lights which ran off a now deceased solar panel.
I use them for camping so have a 12v supply
I've connected them up to a 3.3v power supply and they draw 160mA
What value of resistor do I need to run them off a 12v supply and how
much current (or power) will the lights and resistor draw together?
Many thanks

Nick
