Hi m@[tador], I just want to check that I am at the serial routine here, since it seems to be manipulating the right data but doesnt seem to be doing much with the different results..

The program goes into a loop and takes each character from the serial and compares with the letter 'a'.. I have tried this loop with letter > a, < a and =a and none seem to be any good in the end :\
