I'm trying to print messages to the serial monitor, and all I get is some unreadable format.

Looping Serial.println("Wait...!"); gives me the following results: 

ö’ö’ƒÕ•¬­ƒ´¼Õƒö­“ƒ²ƒƒƒ¬‘¼¬Õ”’­­“ƒ¬•

Why is it unreadable, and how do I make it print a readable format?

    By printing at the same baud rate that you are reading at? – Majenko♦ Oct 27 '16 at 18:35
  • Please show the code that initializes the Serial communication (Serial.begin(...)). Then show the settings of your serial monitor. I think just doing that should give you the solution. – jfpoilpret Oct 27 '16 at 18:52

This "weird" result usualy happens when you select then wrong baud rate or a different one then the one you beginned the serial communication with in the program. Thus by using Serial.begin(9600);, you have to make sure that the serial monitor is actually set to a baud rate of 9600.

  • Thanks! I had no idea what baud rate is, but I figured it out with your answer – Berit Larsen Oct 27 '16 at 18:55
