Hello
This is probably the simplest question ever posted here and I apologise to all you experts
The thing is I am developing a product which will incorporate one or more LED lamps and I want to find a way of trying various options such as size and colour of different lamps
So I went to Maplins, bought a selection of little packets of LED lamps, some wire and a load of AA batteries and started connecting them but and nothing happened, no sign of light whatsoever. So, I read on here somewhere that you need a resistor and so I went back to Maplins (has anyone ever tried asking any of their staff anything? "Dunno really" seems the default response to any question) and got some resistors and put one into the circuit but still nothing
Can anyone tell me how I can light an LED using one or more AA batteries
As I said a very dumb question but for me a complete and utter mystery!
Thanks for any help.
