Lub timer yog lub sijhawm ua haujlwm uas ua rau ib qho kev nqis tes ua ntawm lub sijhawm teeb tsa. Nws yog dav siv nyob rau hauv cov haujlwm ua haujlwm, kos tshuab, thiab kev siv cov ntawv thov. Hauv kev ua haujlwm, cov thawj coj tau tswj hwm los ntawm cov ntsiav tshuaj thiab siv los ua haujlwm tsis tu ncua (xws li kuaj xyuas cov xwm txheej nyuaj thiab ua kom rov qab teb qeeb. Raug raug yog milliseconds (1-10ms). Hauv cov cav, cov neeg tswj hwm tau siv rau kev tswj vaj khoom (xws li sensor cov ntaub ntawv tau txais thiab tsav tsheb), xav tau kev ntseeg siab (ua yuam kev<0.1%) and real-time performance. In application development, timers support delayed tasks (e.g., executing after 30 seconds) or periodic tasks (e.g., triggering every 5 minutes), improving program automation efficiency.
