3 digit counter module / Jefrry Mohd Noor and Izwan Iskandar Ahmad

A counter is one of the most useful and versatile subsystems in a digital system. A counter driven by a clock can be used to count the number of clock cycles. Since the clock pulses occur at known intervals, the counters can be used as an instrument for measuring time and therefore period or frequency. Our project is 3-digit counter module, which is capable of counting input pulses from 1 up to 999. It consists of two buttons, which is start and reset. It is widely used in digital voltmeters, frequency counters where a decimal count is needed It can also act as an electronic rosary. We believe that this project can give benefit to our daily lives and just acquires a small budget.
