it exceeds the 900 chaector length I will try and just include the upper half... I apologize I am new to this

/**

  • Description:
  • This is an example sketch that builds an Alarm Clock out of an Arduino Uno,
  • an LCD Keypad Shield, a DS1307 Real Time Clock, and a buzzer
  • The example lets you display the date and time, and also set the alarm.
  • There are 4 modes of operation in which the buttons on the LCD have specific functions.
  • "Display Date Time" mode: Date, Time, and an Alarm indication display on the LCD (default mode)
  • SELECT: Lets you set the alarm time
  • LEFT: Displays the current alarm time
  • RIGHT: Turns the alarm on and off
  • "Display Alarm Time":
  • No active buttons. After 3 seconds the clock returns to the default mode
  • "Set Alarm" mode: Lets you set the alarm time (hours & minutes)
  • UP: Increases hours/minutes **
  • DOWN: Decreases hours/minutes **
  • SELECT: Accepts the hours/minutes value
  • "Buzzer Ringing" mode: When the alarm time has been met, the buzzer rings
  • SELECT or LEFT: Turns off the buzzer and the alarm
  • UP or DOWN: Snooze -> Adds 10 minutes to the alarm time
  • ** After 5 seconds of inactivity, the clock returns to default mode
  • Note 1:
  • The development of the code was based on a Finite State Machine (FSM)
  • you can find on github: GitHub - nlamprian/AlarmClock: Arduino sketch that makes use of an LCD Keypad Shield and a DS1307 RTC to build an alarm clock
  • The code is quite simple and was made possible due to the above
  • preliminary design. You are urged to study both the FSM and the code.
  • Note 2:
  • The time on the RTC can shift over time. If you notice a deviation building up,
  • just uncomment line 91 and load the example to your Arduino. That will set the
  • computer's time on the RTC. Afterwards, make sure to reupload the code with
  • line 91 commented out. If you don't do that, the next time your Arduino resets
  • it will write the time again on the RTC... the time of the code's compilation.
