Recently i came to understand the true demand for a multi purpose digital pulse counter. so i designed an east to build digital pulse counter circuit based on some generally available cheap electronic components. the quick microcontroller based design comprises of the following: digispark attiny85 development board (original clone). 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. It is a cmos seven segment counter ic and can be operated at very low power. it is a decade counter, counts in decimal digits (0 9). it is used to display numbers on seven segment displays and it increment the number by one, when a clock pulse is applied to its pin 1. means more the clock pulse rate, faster the numbers change in 7 segment display. The 74ls90 integrated circuit is basically a mod 10 decade counter that produces a bcd output code. the 74ls90 consists of four master slave jk flip flops internally connected to provide a mod 2 (count to 2) counter and a mod 5 (count to 5) counter. the 74ls90 has one independent toggle jk flip flop driven by the clk a input and three toggle jk. Each pulse applied to the clock input increments or decrements the number in the counter. a counter circuit is usually constructed of several flip flops connected in a cascade. counters are a very widely used component in digital circuits, and are manufactured as separate integrated circuits and also incorporated as parts of larger integrated.

I am try to make simple pulse counter using arduino uno board, so i find following link where write "simple circuit that counts pulses, and reports it through the serial monitor. this circuit counts pulses fed into pin 12. in this circuit, the pulses are generated by a push button. the arduino checks the state of pin 12 every one millisecond. if pin 12 goes high, the arduino will count it as a. In a simple digital logic solution, using probably a fairly modest cpld, the digital pulse could clock a counter. the size (number of bits) of the counter depends on the maximum frequency you want to measure. a clock circuit would be needed to generate a pulse every 7.5 seconds.
