Cost Analysis of Stopwatch Circuits Made with Arduino Development Board and Digital Integrated Circuits.

Applications such as stopwatch, digital clock and counter are among the most frequently used applications in the digital world. In this study, we focus on the stopwatch circuit by taking it as an example. The main function of a stopwatch is to keep, control and manage time. The goal here is how to design and realize a low cost, power efficient and less latency stopwatch. In this project, the 4-digit up counter was designed and implemented using Arduino development board and classical digital circuit elements. It was also simulated using the Proteus package program. A comparison was made between the two presented methods in terms of cost, performance and power consumption. As a result of the comparison, the lowest cost, highest performance and least power consumption were obtained from the circuit made using classical digital integrated circuits. Therefore, digital systems designed with classical digital integration are much more advantageous, especially when mass production is needed.
