flip-flop 2

THE FLIP FLOP

This is the simplest circuit capable of alternately flashing two LEDs. The flash-rate is determined by the two 10k resistors and two 100u electrolytics.

The flash-rate can be increased or decreased and one LED can be made to flash brighter by altering the 4 components.

This circuit does not have the advantage of the two described above. It does not pulse the LED with a high current for a short period of time and thus it is not as efficient as the two above. When a LED is pulsed with a high current for a very short period of time, the output is almost as bright as a constant, lower-current.
