Trouble with using encoder and pid library together

it seems the sprintf functions I was using for the lcd display was creating the problem. removing those has solved the problem.

Your sprintf() statement is likely overflowing the timeBuffer array. Why did you only reserve 6 bytes?

  char timeBuffer[6];
  sprintf(timeBuffer, "%3lu:%02lu", programtimeminutes, programtimeseconds);
