I hope there is someone who will assist me with this. I have 5 LEDs, with a switch in front of them. I use a 12v supply. Switches can be randomly turned on or off. LED's are 2v, 10 mA.
I can not get my head around how it should be assembled. I am afraid to send too much current through the LED's. Should I put a resistor in front of the LED's?
You can probably read that I am not very good at electronics. But when has it stopped anyone :)
Thank you in advance.
I am very sorry I have written something wrong. There is a switch in front of each LED. So each of them can be switched on and off. Again, I'm sorry, and thanks for the replys.
