The circuit using ics 4518, 4511, and a common cathode display is a binary counter with a decimal output. it can count from 0 to 99 and display the count on a 7 segment display. the ic 4518 is a dual bcd (binary coded decimal) up counter, which means it can count up in decimal from 0 to 99. the two counters are cascaded so that the second. The highly recommended 00 99 digital counter turns into easy to carry in places where you require to keep the people organized in some particular order. functioning information of the digital counter as could be known as the circuit uses the widely used 555 ic to genearte the pulse clocks. the pulse counting is conducted with the aid of sw1.
In this tutorial, we'll see about how to make 0 99 counter with cd4026 counter ic,different clock pulse input & demonstration. this circuit is based on 4026,. 2 digit bcd counter from 00 to 99. bcd counter summary. in this tutorial we have seen that a bcd counter is a devices that goes through a sequence of ten states when it is clocked and returns to 0 after the count of 9. in our simple example above, the input clock pulses are from a push button switch but counters can be used to count many real. This circuit can be used in various projects where we require the counting. like in doctors’ clinic or hospitals, in restaurants, in customer care offices where long queue is there and we want to stop the rush at the counter. this system is very effective where man power is less. in this you have to provide a token to the person and the person has to wait for its turn which can be displayed. In the 555 timer pin 2,6 and 7 are shorted and connected to the capacitor c1. pin 4 and 8 are connected to vcc. pin 3 is the output pin. in the case of cd4033 ic pin 1 is the clock input. pin 15 is the reset pin, by applying vcc you can reset the count to 0. pin 6,7,9,10,11,12,13 are given to the seven segment display.
