Sure, get some 15,000mCD LEDs from www.mpa.com, some current limit resistors, and write a brief sketch that will turn an output or 3 or 4 on & off. Pretty simple.http://www.mpja.com/prodinfo.asp?number=15415+OPThese things are super bright - do not stare at them!Where are you located?
I know while doing automotive electrical you can get a relay that powers high powered spotlights with minimal strain on the switch itself. Is there any such thing for LEDs??
kleggy, can you give us any details on the LEDs you bought?Liudr, totally off topic, how many pins were on that signetic 87C451 I sent you? Was it 68? More? I can't find the data sheet I had, did I send you a copy?
Nice documentation on those.Now, since you are making a strobe, the assumption would be that you switch them at the same time?What do you have for a power source?If you could connect these in series from say a 30V source, then you could have 8 in a string with a 20mA current limit resistor, then make a bunch of strings.The strings could all be connected in parallel and switched with a single N-type transistor, NPN or N-channel MOSFET.Control Base/Gate from the arduino. Or a simple 555 timer with a potentiometer to control the frequency.Some examples here
