I noticed something unusual using the Low Power library today. When printing text in the loop and using LowPower.powerDown(SLEEP_1S, ADC_OFF, BOD_OFF); to sleep for one second, all the text in the loop gets messed up in the Serial Monitor as if you chose the wrong baud rate.

Example code:

#include "LowPower.h"

void setup() {
  Serial.begin(9600);
  Serial.println(F("HELLO"));
  Serial.println(F("HELLO")); 
}

void loop() {
  Serial.println(F("HELLO"));
  LowPower.powerDown(SLEEP_1S, ADC_OFF, BOD_OFF);
}

This code just prints

����11=C!�11=C!�11=C!�11=C!�11=C!�11=C!�11=C!�11=C!�11=C!�11=C!�11=C!�11=C!�11=C!�11=C!�11=C!�11=C!�11=C!�11=C!�11=C!�11=C!�11=C!�11=C!�11=C!�11=

even when using different baud rates. (I used the same baud rate on both the arduino and the monitor). Replacing the low power command with delay(1000); works fine
