Hi all, first post here, and I have a few questions. I am attempting to make a LED array to custom light a scale model project. I need to run 11 LEDs off of a 12v source, so I was thinking of running them in series parallel, with four separate legs to the circuit. The first leg will have 4 red LEDs (2v 30mA) and a 150Ω resistor, second leg - 3 blue LEDs (3.6v 30mA) 47Ω resistor, third leg - 2 white LEDs (3.6v 30mA) 180Ω resistor, fourth and final leg - 3 LEDs (3.6v 30mA) with a 47Ω resistor. All resistors are 1/4w, P/S is 12v (8 AA battery) . So my question is will this work? And if so should there be a current regulator in the circuit to maintain a steady 30 mA? If yes will one regulator be ok for it or should each leg have it's own?
Thanks for any help or feedback. It has been about 20 years since I played with trons, and as the saying goes, if you don't use it you loose it. I have forgotten more than I remember
