Greetings,
I am rather clueless about this stuff so I'll leave it to you guys to come up with any bright ideas for this. I'm building an array of LED's for my high school that flash to music. I'm using a TIP31C transistor to get this effect. My problem is they're wanting a 1 foot by 1 foot array. I figure i can put about 50 LEDs in it, but I'm going to need to use AC current to get the necessary power. The LEDs i have are rated at a 3.3 - 3.8v forward voltage; they're just cheap green 5mm LEDs. So I know I'll have to convert the AC to DC and use a voltage regulator so I don't burn out my LEDs, but other than that, I'm clueless. What can I do to make this work efficiently and what can I do to prevent it from being destroyed by the power? Also can the transistor handle that kind of current?
Thanks
