Each of the codes works independently, but I cannot A while loop will loop continuously, and infinitely, until the expression inside the parenthesis, becomes false. If you were fast enough to transmit one full character before the first check occurs (eg by adding delay(10000) to the setup() function) you will get one Hello and end up in endless loop #1. I did't post my code because it is really long and hard to understand. Example Code. while (millis() - screentime <= 0) You don't need the 'time' variable because you're only interested in the current millis() time and there's no need to save it. Something must change the tested variable, or the while loop will never exit. Thus the code in the body will run at least once, even if the loop condition is initially true or false.
