How is this data being formed from the values given?

[Jerson]

After a little analyses, this is what I got

Output numbers = (Vin-10)*126 (could be more like 128 as it is then a left shift operation)
So, converting into a table, this is what I see


Hope this helps

there's few things the arduino community have not hacked into if its at all possible
a google search for "arduino & 'my secret unmentionable device' " might yield some results
