Sorry I changed the wrong 0 in my rush to test and get out of the house last night and as you say it compiles and work fine if I use "0"
As this is the distributed example is it worth letting Arduino know?
AWOL
Could you explain %10 as I was unable to find any reference to it.
I assume it's means if it's divisible by 10 but I can't work out the syntax
