Make a LED turn on for variable times, including 1/60, 1/120 and 1/500 of a second? Answered

You guys probably already know, I'm making a flash for photography. To do so, the flash has to "flash" very quickly. Does anyone know a component that will be able to make the LED "blink" in that amount to measured time?

Thanks in advance,

James

A microprocessor is the best way and you would get a real precision with it. I would advice you to go with a arduino, as it is really simple to program a blinking led.

As for the bright light I would agree with rickharris.

Unless you need real precision I would go for a simple 555 timer.

I would expect though your going to want a very bright light? that is hard to get with LEDs that's why they still use a Xenon flash tube.

A micro processor running on straight machine language.

No basic, no 'C'
