Variable not incrementing correctly

If the following code may be a problem because you are mixing && with || without grouping:

(tiktok >= 1) && (tiktok <= 8) ||
(tiktok >= 10) && (tiktok <= 14) ||
(tiktok >= 16) && (tiktok <= 19)

It should probably be "(( tiktok>=1 ) && ( tiktok <= 8 )) || (( tiktok >= 10 ) && ( tiktok <= 14 ))" and so on.

You should also consider to write your values as a single line for simplicity:

Serial.print(tiktok);
Serial.print(" ");
Serial.print(motState);
Serial.print(" ");
Serial.println(tune);
