Beat Timer
Can anyone design me a circuit that when a button is pressed at intervals the device displays on a LED what the beats per second were? And change as the rate of pressings change. Thus if the button is pressed with 1 second intervals the LED display would show "60". Range up to 60 beats/sec only and small enough to fit inside a hand held stopwatch sized enclosure. Accuracy is not important - within 5%.
