// Variables

int sleepmode = 0; //Triggers when sleepmode is activated. If motion is sensed, turns on lights to dim setting, similar to a night light
//int secflag = 0; //Security System flag- similar to ppl variable, security system activates when both members have left GPS area

// setup() is run only once, it's where we set up GPIO and initialise peripherals
