c_cpp

for this you will need to download arduino IDE RTC library zip file, seven segment zip file save both of the libraries into the librarys folder where the arduino ide is installed. from there open up arduino ide and click on 'sketch' 'include libraries' 'add zip libraries' follow the code below TO ADJUST TIME - on line 7 in the brackets it reads (2017, 12 , 9, 0, 0, 0,) you need to change the first 3 numbers i.e 2017, 12, 9 ----> 2014, 4, 6, what ever date you got together, enter it there. then compile and select upload and if everything has gone to plan and you've followed the steps correctly it should display the amount of days you have been together
