12 minute timer will count for 720 seconds. When the timer is up, the timer will start to blink. You can pause and resume the timer anytime you want by clicking the timer controls. To run stopwatch press 'Start Timer' button. Online countdown timer alarms you in twelve minute. If the input is all good then, else block of our function will return an OK. 12 minute timer to set alarm for 12 minute minute from now.Next two conditional statements do the same job as the first, comparing minutes & seconds respectively.But if the input is more than 12 hours, then it will return a statement asking the user to re-enter the time. The input is not more than 12 hours then the execution will move forward to the next conditional statement. Here at alarm_time, we are using a slicing operator to access the first two characters of user input. There could be a slight chance that user may enter invalid hour values like something more than 12 hours. In the first if statement within else block, we are validating the first two characters of our input which are HH.If the user input is exactly 11 characters long, then else block will execute, this is where the more in-depth validation of our user input happens. If not then it will return a statement, asking the user to re-enter the value. In first if statement, at len(alarm_time) != 11 we are checking the length of user input to be exactly 11 characters.Our function accepts the user input as a parameter alarm_time.Let's break it down and understand what is going on. Here is our function called validate_time.
#Set alarm 12 minutes install
Let's run pip install command and download both of these modules.Įnter fullscreen mode Exit fullscreen mode
We need 2 different modules for our project - datetime & playsound. All you have to do is run a simple pip install command from terminal & our specified module will be downloaded in our system. All we have to do is import them into our project to get started. These modules will help us save a lot of time and effort. In this project, we are going to use some external modules which are already made available by other developers. The alarm clock we will be building will follow the same mechanism. This is a very general idea of how usually an real alarm clock works. As soon as both the time matches, the alarm rings. Once you have set your preferred time, the alarm will continuously match the time you provided with the current time. Welcome everyone, today we are going to build an Alarm Clock using Python.Īn alarm clock usually requires you to set the specific time you want the alarm to ring.
