Millis (); won't work properly

[Coding_Badly]

@erickcs

const long PERIOD1 = 25;  // interval at which to blink (microseconds) = 20 Hz
const long PERIOD2 = 12.5;  // interval at which to blink (microseconds) = 40 Hz
const long PERIODact = 5000;  // amount of time to keep blinking (milliseconds)
const long PERIODbtn = 150;  // (microseconds)

Wrong datatype.
