Ah, well in that case you're going to need to add the declarations for the delays as global variables (ie at the top, outside of the setup() or loop() functions. They might look something like this:
// since negatives aren't going to be used, unsigned integer type gives twice the maximum size of normal integers
unsigned int a = 1000; // 1 sec
unsigned int b = 1500; // 1.5 sec
unsigned int c = 10000; // 10 sec
unsigned int d = 5500; // 5.5 sec
unsigned int e = 65535; // if using unsigned integer type that's the max
unsigned int f = 5; // 5ms
or for the array example I gave the same would look like:
unsigned int valueArray[6] = { 1000, 1500, 10000, 5500, 65535, 5};
In both code examples I've got your LCD displaying two variables, one per LCD row, waiting half a second then displaying the next 2.
Hopefully this puts you in the right direction. Cheers ! Geoff
