dc42Thank you very much for your fast answer! - the 240mA is per color, therefore the pwm pins can't handle this. I am NOT going to use SMD components. I would like to ask you, why you would use a transistor rather than a mosfet? - is it just because the transistor is cheaper, or does it have some capabilities i will need, as the mosfet doesn't offer. I am asking because i red somewhere that mosfets are more generally used today, therefore i thought that this would be the best thing to use :-)again, thank you very much. I appreciate your help
Pretty much any transistor will do.
Quote from: fungus on Dec 23, 2012, 09:29 pmPretty much any transistor will do.I disagree, you need a transistor with reasonable hfe and low saturation voltage @ 240mA. Low-current types such as 2N3904 would not work well in this application.
Damn, you found an exception!I'd better name one: 2N2222 (or BC548 for Europeans)
The reason I like BC337
shall i use a Transistor or a Mosfet?
