How to Build an LED Flasher Circuit with a 555 Timer Chip LED Flasher Circuit. Again, as an example, if we set our duty cycle to be 20%, this means the LED will flash on for 20% of the cycle and be off for 80% of the cycle. If we choose a duty cycle of 80%, the LED will be on for 80% of the cycle and off for 20% of the cycle. Thus, our duty cycle is very important.
