// alarm receiver by gianmarco
// rev 0.5 20150122 - cleaned up code, added selective alarms and night mode
// rev 0.6 20150123 - added reset display, selective alarms tested
// rev 0.7 20150809 - changed a few details
// rev 0.8 20150915 - changed beeper type, introduced time limits for night mode
// rev 0.81 20151211 - added alarms
//
// add this as reminder
// boolean (8 bit) - simple logical true/false
// byte (8 bit) - unsigned number from 0-255
// char (8 bit) - signed number from -128 to 127. The compiler will attempt to interpret this data type as a character in some circumstances, which may yield unexpected results
// unsigned char (8 bit) - same as ‘byte’; if this is what you’re after, you should use ‘byte’ instead, for reasons of clarity
// word (16 bit) - unsigned number from 0-65535
// unsigned int (16 bit)- the same as ‘word’. Use ‘word’ instead for clarity and brevity
// int (16 bit) - signed number from -32768 to 32767. This is most commonly what you see used for general purpose variables in Arduino example code provided with the IDE
// unsigned long (32 bit) - unsigned number from 0-4,294,967,295. The most common usage of this is to store the result of the millis() function, which returns the number of milliseconds the current code has been running
// long (32 bit) - signed number from -2,147,483,648 to 2,147,483,647
// float (32 bit) - signed number from -3.4028235E38 to 3.4028235E38. Floating point on the Arduino is not native; the compiler has to jump through hoops to make it work. If you can avoid it, you should. We’ll touch on this later.
