Replaced "if" with "#if", changed int to uint32_t

Browse Source 
Replaced if statements with #if preprocessor macros.
Replaced one #ifdef macro with #if.
Changed `int secondTimer` to `uint32_t secondTimer` to avoid signed/unsigned integer comparison. The `millis()` function returns `uint32_t`.
Removed asterix output from FPS output.
