I dont know if 0 to Z have its own 4bit desc. Idk
CAUTION: Counting sync may be an issue for mobile phones with lower CPU cores. (1 second sync runs mostly on 1.6Ghz. Any faster than that may cause counting sync issues (0.6492 spt to be exact on 3.0GHZ CPU.) ) So please set capacitor voltage to 1nF if your CPU is running at 3GHZ
UPDATE: I somehow add a reset if the SUM reaches 9 to stop it counting to A or whatever
UPDATE2: I add 1more 7segment to count from 0 to 9F after that it reaches 0.
PLEASE: Write me some suggestions. Any suggestions
