- Countdown timer with Display (does not display the timer countdown at first) - Time Value for timer Random between 2 values set by user via keypad at start - Once the timer reaches 0, buzzer sounds for 10s, then timer restarts (Infinite Loop) - Keypad to enter a defined 4 digit code that will activate the display and show the countdown timer counting down for X amount of time - Keypad defined 4 digit codes that reduce the remaining countdown timer by X amount (depending which code is entered) but that, once countdown completed, doesnt impede the regular loop of the randomized timer) *** 1- i flip a toggle switch, the circuit turns on 2- the LCD display asks me to input min value (in minutes) 3- then the LCD display asks me to input max value (in minutes) 4- The LCD asks for the codes, one by one (LCD, 1min, 5min, 7min) 5- when i confirm the min/max values, and all the codes, the timer starts (random value chosen between the min/max values set at start) 6- when the timer reaches 0, buzzer for 10 seconds 7- Loop the entire process infinitely (do not ask for min max values, loop the timer circuit using the same min max values but another random value between min/max) 8- *** during the countdown of this timer, I do not want the display to show the time remaining*** 9- At any point during the circuit, I want to be able to enter a 4 digit code which will trigger the display to show the timer indefinitely, even after the timer ends and the loops a new timer. I want, when this code is entered, that the display show the timer time until i close and restart the circuit.
