Arduino UNO sketch for hardware Pomodoro timer for ATMega328P Boards

I use an online tool called PomoFocus for my pomodoro timer but the issue is that I spend more time looking at the time and pausing it rather than doing my work so I decided to make my own appliance for it using Arduino UNO so that I can focus on my work instead of looking at the timer because the timer isn't visible now! I can work until the buzzer beeps.

• When the board is connected to power, it gives a pomodoro starting buzz and the built in board LED blinks every second to indicate the focus timer.
• After 25 mins, there will be a long buzz after which, the light blinks once every 3 seconds indicating break time.
• Break time lasts for 5 mins, after which, the buzzer goes back to starting buzz
