Now i will print out : Serial.println(myStartString + “with plus sign”); Run to see what’s happend. Instead, we will create another String String myCombine = myWelcomeString + myStartString; And then put to Serial.println(myCombine); ...
To concatenate strings means to combine two or more strings into a single string. This can be particularly useful when you want to create custom messages, display information, or communicate with external devices.
