Simple Arduino Alarm Clock Project -- 2

Project Details You are expected to do the whole project solely on Tinkercad, but for those who prefer to use Proteus can also use it. (One advantage of Proteus is having more options to choose from for most components.) You are NOT restricted to using register operations, you can use any kind of code including libraries for components (i.e. Wire.h, LiquidCrystal.h). But YOU MUST USE TIMER for timing. Do not use delay function for timing. Requirements - LCD screen which is showing: 1-Current time (Switchable between “00:00-24:00” and “00-12 AM/PM”) 2-Alarm time (with a symbol indicating ON/OFF) 3-Temperature (Switchable between Celsius and Fahrenheit) -4 Buttons which are used for: B1-Switching between modes in current time (Hold 3 seconds for current time setup) B2- Setting the alarm ON and OFF (Hold 3 seconds for alarm time setup) B3-Switching between temperature scales (Fahrenheit /Celcius) (During a value setup, this button acts as “raise value ^”) B4-Snooze button (Temporarily stops alarm for only 5 minutes) - Piezo buzzer for the alarm sound - Potentiometer for changing backlight brightness - Temperature sensor for detecting temperature - You must use TIMERS for timing (i.e. do not use delay function to update seconds) To see which value is being set at a given time, the time value which is being set will blink. Here is an example setup scenario of setting up alarm time: Alarm Set Up 1-Hold B2 for 3 seconds to start setup *alarm minute will blink* 2-Use B3 to adjust alarm minute 3-Press B2 once to switch to hour *alarm hour will blink* 4-Use B3 to adjust alarm hour 5-Press B2 again to end setup Clock Set Up 1-Hold B1 for 3 seconds to start setup *clock minute will blink* 2-Use B3 to adjust alarm minute 3-Press B1 once to switch to hour *clock hour will blink* 4-Use B3 to adjust alarm hour 5-Press B1 again to end setup
