How does a digital countdown timer works?
a digital countdown timer is simply a digital synchronous counter consisting of registers and flip flops example :to count the number from 0 to 15 we require a four bit synchronous counter which will pass to sixteen stages continuously with shifting from one stage to other after every clock pulse and the cycle continues
How working of the microcontroller baesd industril timer?
There are different types of industrial timer like ON Timer, OFF timer, Cyclic Timer, sequential timer there basic function is the same to turn ON/OFF devices at particular time or after a specific durations check this link for a simple microcontroller based ON timer where where a device is turned ON for a specific duration after a switch is pressed http://www.dnatechindia.com/index.php/Code-Library/8051_ASSEMBLY/ON-Timer-Program.html here is another link for adjustable cyclic timer where a device is turned ON/OFF continuously for a specific duration http://www.dnatechindia.com/index.php/Kits/Microcontroller-Kits/Adjustable-Cyclic-Timer.html
Timer in Flash - How to stop it?
Hello,I am learning how to make a timer to my game. It is something like "Who wants to be a millionaire?" I have 15 questions. There is timer for each question:60 seconds....

What is software timer?
There are two types of timers: Hardware and Software. Hardware timer is a small logic circuit with small piece of specific crystal which generate pulse at specific frequency. The problem with this kind of timer is that there are only a few of them in computer boards (some decades they did not use timer at all and instead electrical lines there used which was running precisely at 50Hz) and you might want to have more timers in your system. And here comes the software timer. Software timer is a descriptor in global timers table where all timers are checked every time hardware timer is triggered. For example you have table (let it be your global timer table): |Timer Id|Pointer to function|Time out|Init. value|Loop| | 1 | checkIO | 1000 | 1000 |No | | 2 | CleanBuffer | 9000 | 9000 |Yes | | .... Note: "Time out" and "Init. value" is in milliseconds. Let's say my hardware timer is running at 1MHz, which means it is triggered a thousand times a second. Each time hardware timer is triggered I will be checking table to see if "Time out" column is equal to zero, if so I call function which pointer I have saved in "Pointer to function" column. If "Loop" is Yes "Time out" column is set to "Init. value". If "Loop" is No timer record from global timers table is removed. This is very simple implementation of software timer. This was used only for example to better understand the difference of hardware and software timers.
Why does your water softener keep on draining?
That's not normal. The timer may be stuck in the regeneration cycle.
Why does frig cycle off only seconds after it cycles on?
Fridge timer probably needs to be replaced!
Why does the dishwasher stay in wash cycle and makes a clicking noise and does not go to rinse cycle?
Why does my 950 series frigidaire dishwasher stay in wash cycle and make a clicking noise and does not go in to rinse cycle? ANS 2 - The timer is faulty. It's unlikely you can fix the timer, but not too difficult to fit a new one. ( only cost -effective if the dishwasher is a really good and almost new one. )
Can a defective central timer module affect intermitent wipers on a 2005 dodge ram 1500?
A 2005 doesn't have a central timer module. The wipers are controlled by the cluster and the front control module. 1994-2002 did have a centrel timer that did control wipers.
Does steam affect the accuracy of a cooking timer if its left by the stove for an hour or longer?
In theory, steam could affect the timer because if it's left for a long time and the metal heats and expands it could slow down slightly. The likelihood is very slim.
What is fuel oil mixture for a 1991 Johnson two stroke?
Most late model Johnson/Evinrude outboards carry a decal stating a 100:1 ratio. Being an old timer, I still prefer the ol tried and true 50:1 ratio, one pint of 2 cycle oil to six gallons of fuel. Never seen a powerhead failure due to the richer oil mix.
What are common features on breadmakers?
Breadmakers need to have a basic cycle and a dough cycle. It is also important to have a delay timer and keep warm feature. There are other optional features such as crust control depending on what the needs are.
Hoover washing machine - NextraOptima what does a red flashing light on start-delay start mean Is it pump gone?
A red flashing light on the Hoover Nextra Optima washing machine when the start delay timer is set might mean that the timer itself is not operational. Run the washer on the regular cycle, and if it works fine, it is the delay timer.
