Digital counters are electronic devices that display numerical values, often used to count items, events, or time. They convert physical quantities, such as the number of people entering a building or the time elapsed in a race, into a digital format that can be easily read on a screen. These counters can be found in various applications, from simple handheld devices to complex systems in industrial settings. They often use LED or LCD screens for visibility and can be programmed to perform specific functions, such as resetting or incrementing counts automatically.
