Get your Arduino ready with a 7-segment LED, a buzzer, and two push-buttons.
You are making a melody timer
The 7-segment LED will display the time (set time or remaining time).
First push-button is the Set-time button. Pressing it increases the Set-time by 1 (second). If the Set-time reaches 9, pressing the button will reset it to 0.
Second push-button is the Start button. Pressing it will start countdown, so the displayed number should start decreasing.
When the time is up, the buzzer should let you know.
