4017 And 555 Circuit Diagram. Every time the clock input goes high the counter in the 4017 increases which makes the next output high. Vcc 8 th pin and gnd 1 st pin is connected to the power supply.
The led chaser circuit is basically a serial switching of led s in a continuous manner. When it to pin 11 the output light will back to pin 3 and continue to glow in sequence each step by the signal from ic 555 in the circuit. Every time the clock input goes high the counter in the 4017 increases which makes the next output high.
But it is difficult and boring.
The output frequency of the 555 timer is determined by the resistors r1 rv1 and capacitor c1. Led chaser circuit using 555 and 4017. It used in computer games and in many scientific and mathematics applications. The main part of this led chaser circuit diagram is 555 timer ic which generates some variable frequency.
