Hello i'm very new to arduino just bought my board today
Here is what I want to build.
I want to turn the device on with a key so it can not be turned off
then a timer will start to count down lets say 10 minutes
once this timer runs out I want the display to flash and count down for lets say another 5 minutes
once the second timer runs out I want an alarm to sound
but I also want a button so these timers can be reset to the start at any time unless the timers run out and if so the key is required to reset the timers
any help is very appreciated and remember please keep replies a simple as possible total newbie here

please keep replies a simple as possible total newbie here
Is that simple enough for you ?
We don't mind helping you but we won't do all of the work for you. Please post what you've already done including any ideas you've had and we might be able to make some suggestions. If you've got completely no idea then maybe it's your lecturer’s fault and it isn't right that you make him/her look good by cheating and copying from the Internet.
