Arduino Project (Code)

Good day. I would like to make a puzzle bomb. I have the following hardware that I would like to use to run the program: Arduino Uno or Mega 5110 LCD Display DS3231 Real time clock 5 Photo resistors Hall effect sesnor Buzzer module/speaker The timer counts down for 60 minutes. Displayed in large numbers with minutes and second (timed from real time clock not from a delay function). The program starts to run when the magnet is moved away from the hall sensor. Placing the magnet back must not stop the program. Once the timer is started there must only be one way to stop it. There are 5 photo resistors which need to be on the PWM pins or analogue pins. The person solving the puzzle will have a laser pointer. They will "cut" the wires in the correct order. The cutting is pointing the laser at the photo resistor. There will be a sequence to follow. So from A1-A5 pins. If the incorrect sequence is entered the buzzer makes a noise and they lose 1 minute of time. The buzzer will tick like a clock on each second. Every 15 minutes it makes a tone sound.
