Timers & Real-Time Clocks

Timers and real-time clocks (RTCs) are electronic devices that are used to measure and track time intervals in electronic systems. They are crucial components in many applications, such as control systems, automation systems, and consumer electronics.

A timer is an electronic device that is used to measure the duration of time intervals. Timers can be either digital or analog and can be used to measure time intervals ranging from microseconds to hours or even days. They can be used for a variety of applications, such as controlling the duration of a signal or triggering an event after a specified time interval.

A real-time clock (RTC) is a clock that keeps track of the current time and date. Unlike a timer, an RTC is capable of keeping track of time even when the system is powered off. RTCs are commonly used in consumer electronics such as watches, clocks, and digital cameras, as well as in control systems, data loggers, and other applications that require accurate timekeeping.
