Hi all im hopeing i have put this in the right section but i need some help.
I feel its about time i learnt a bit more about electrics does anyone no of any step by step guides on how to build stuff that explains what the components are for or just a list of components and what they do.
At the moment i am attempting to add some leds to my Xbox controllers and ive been hit with this Ohm resistor what the hell is one of them i no what they look like but what do they do it says
Lighting the Dome- To get the dome illuminated we tried several variations, one LED, two LED's, but ended up going with four for full bling. With blue LED's, 4 in parallel a 22 Ohm resistor is connected to all positive legs and the resistor is connected to the positive source. All negative legs (short ones) are connected to ground. When using 4 red LED's a 47 Ohm resistor was used (How to calculate the proper resistor for your LED's).
I know what parrel circuits are but how did they get 22 ohm im at a lose please help me .
