interrupts frequently can affect the system’s clock. Explain why this can occur and how such effects can be minimized. Answer: The system clock is updated at every clock interrupt. If interrupts were disabled —particularly for a long period of time —it is possible the system clock could easily lose the correct time. The system clock is also used for scheduling purposes. For example‚ the time quantum for a process is expressed as a number of clock ticks. At every clock interrupt‚ the scheduler determines if

This system switches on the lights only at preprogrammed timings. As the DS1307 Real Time Clock chip with battery back-up is used‚ there will be no disturbances for the programmed on/off timings even in power failures. Three switches are provided for entering the required timings. These switches made this project user friendly. 16X2 LCD display

When no light is falling on LDR1‚ its voltage drops below 1V and IC1 output at its pin 1 becomes high.

biological clock. But this can be overridden by psychological factors such as anxiety. An endogenous (internal) clock (or set of clocks) is proposed as some sort of innate mechanism that sets the timing of biological rhythms. Their “tick” may be a 24-hour one‚ which is the case for the sleep–wake cycle‚ an 8-hour one‚ which is the case for the rhythms of sleep or even a 12-month one‚ as in patterns of hibernation. The suprachiasmatic nucleus (SCN) is the pacemaker of the biological clock in the sleep–wake
