Decade Counter Circuit Diagram. After the counter has reached 9 it starts again from 0 with the next clock pulse. It has 10 output.
It is a 5 stage divide by 10 johnson counter with 10 decoded outputs. The schematic diagram for the decade counter using the 4017 chip is shown below. The first step is to connect power to the 4017 chip.
This the circuit diagram of light led flashing with a show of 10 led.
This is a great chip for making running leds. The first step is to connect power to the 4017 chip. 5v goes into pin 16 of the chip and pin 8 gets grounded. Most commonly available as ic cd7490 contains multiple flip flops to convert bcd to decimal and is incorporated as part of larger integrated circuits.
