Inspiration

The importance of staying in control of the day is one that can be overlooked and we wanted to make this easier for people who do not like keeping phones near them whilst sleeping or just want a dedicated device that can effectively serve as a clock and an alarm.

What it does

This device has 2 modes: Time and Alarm. You can set the time on the LED lit clock and also set alarms at particular times throughout the day.

How I built it

The team used a buzzer as the final output device and has a switch to enable switching of modes between time and alarm. A potentiometer is used in conjunction with the LED screen is user friendly and two buttons are used to set the time and alarms: One to set the hour and the other for minutes. All of these are interfaced with the Arduino.

Challenges I ran into

There are not many challenges here to speak of as this was done online and thus connections were permanent and reliable. Handling the case of dealing with the actual time versus alarm time in the code was quite challenging, however, these 2 states are kept separate and no further challenges were faced.

Accomplishments that I'm proud of

By being able to set the actual time and alarm accurately, the team was able to successfully use this device as a stable clock and an alarm setter. Interfacing these with buttons for ease of use for the user is a key component to making this device attractive and the team is very happy of its outcome.

What I learned

the team learned the importance of using multiple sensors and buttons to create a simple to use but effective product. The more devices used, the harder structuring an organized piece of code is and the team finds that it is very important to outline before you start, the various inputs, outputs, connection lines and possible states that each device may require. Doing this prior to writing code or wiring significantly simplifies any project of this nature.

What's next for Alarm Clock

There are limitless potentials to this. For example an alarm clock could be set which in turn could have a coffee maker go off so that whilst you get out of bed, your coffee is already brewing and waiting for you. More complex sensors could be used and reminders could be set on different LED screens which could pop up when required to. This is just the beginning of an easy to use system for helping you stay ahead of the day. Remember timing is everything and we are happy to share this project with everyone.
