+First line starts writing with time function. Second line lets know to which address to talk to for DIO. The third line is for start writing with I2C.

+ #define DIO 0x42
+ #include <Wire.h>
+In the second line you can fill in how many seconds you want the progress to take. In this example it is 30 seconds.
+The HexMax says the maximum amount that could be given in hexadecimals, what is 255 in decimals. ( In hexadecimals it's FF )
+On the fourth line the code will read with processing which second it is and gives it to the variable FirstSec. ( This will only be read the first time )

+Explanation from the arduino clock:
+First line: Start writing with I2C. Second line: Make IO0 output. Third line: Enable PWM ON outputs.
+After that it calculates what the end amount of seconds is, by counting up the given second value (30 in my example) with first second that got scanned.
