Timers and RTCs
Timers and Real-Time Clocks (RTCs) are electronic devices that are used to measure time or keep track of the current time. They can be found in a wide range of applications, including computers, phones, and appliances. Timers are used to trigger an action after a specific period of time has elapsed. They can be used to control the duration of an event, or to schedule tasks to be performed at a later time. RTCs, on the other hand, are used to maintain accurate time even when the device is powered off. They are often used in devices that need to keep track of the current time and date, such as alarm clocks and smart thermostats.
