Flasher

I need a circuit that will flash a light at fairly accurate regular timed intervals.

Perhaps the easiest might be a battery circuit with LEDs, but flashing a mains-powered light would be OK if easier.

It is for use as a light metronome, so I need to be able to vary it to between 40 and 200 flashes per minute.

Have searched the net: lots of flashing circuits, but none that can be varied in tempo in a reasonably accurate way.

Grateful for any thoughts!

Here's one in the app store... Flash Metronome

Not flashing, but free; there's an online metronome.

Of course, you could always try the flashing metronome projects on this website...

You're quite right - I should have searched harder. Thanks!
