Welcome to the Dice Roll Simulator project. The final version of the project features a dice at the center of the screen and a "Roll dice" button. The button triggers an animation and generates a random number, which is displayed in the center of the dice when clicked, t. Additionally, the number is added to a history list. To achieve this, we used modern CSS to style the dice and added a JavaScript event listener to the button. The listener generates a random number, saves it to an array, and updates the history list.

Pomodoro Timer project image

Pomodoro Timer Project

The objective of this project is to design a Pomodoro timer that features a countdown clock and three functional buttons, namely start, stop, and reset. Upon clicking the start button, the timer will commence counting down from 25 minutes. Should one desire to halt the countdown, the stop button can be pressed. The countdown can be resumed by hitting the start button, and by clicking on the reset button, the timer will reset to 25 mins again. An alert will notify the user when the timer reaches zero. This Pomodoro timer is an ideal tool for individuals seeking to focus on a task for a set amount of time, followed by a break. By implementing this technique, productivity and time management skills can be improved. To create this timer, one must initially grasp the principles of CSS for styling purposes. Next, event listeners will be added to the buttons using JavaScript. Finally, a timer will be established using the SetInterval function in JavaScript.

Simple Stopwatch project image

Simple Stopwatch Project

Welcome to the Stopwatch Project! We will create a timer displayed at the top, along with three buttons - start, stop, and reset. Clicking the START button will begin the timer. The STOP button will pause the timer using a JavaScript method called SetInterval, which can be cleared using clearInterval. The RESET button will reset the timer to zero. If you click STOP and then START again, the timer will continue from the previously elapsed time. We'll start by installing CSS for the buttons' design and hover effects, then use JavaScript to get the browser time, manipulate the content, replace it with the calculated time, and provide the start, stop, and reset functionality.
