break exits the program
switch works with float values
Absence of break causes fall-through

What is the PRIMARY implication of this code on an Arduino board?
for(;;) { digitalWrite(LED_BUILTIN, HIGH); }
LED blinks continuously
LED turns ON once and program exits
LED remains ON and program never exits the loop
