7 Led light running adjust speed by 4017 and 555

4017 Led Pattern-Flasher The circuit uses a 555 timer oscillator to supply clock pulses of a variable frequency to the 4017 decade counter. The decade counter only needs to have three outputs so the fourth output goes into the reset pin to start the cycle all over again. The central red led is always on. […]
