WebAug 1, 2013 · The reason that the Serial.Print () doesn't work within an ISR is that it uses interrupts to pull the characters out of the serial buffer, but interrupts of a certain level are masked within the ISR. What basically happens is that the arduino throws out all other interrupts that are of a lower priority, which Serial.Read () falls into.
