Serial.print("The number is "); prints this: The number is The values (numbers) that you print depend on the type of variable; see Recipe 4.2 for more about this. For example, printing an integer will print its numeric value, so if the variable number is 1, the following code: Seria...
Note: usually you can also useArduino interruptsto know when a button has been pushed. If you do so,don’t use the Serial library in the interrupt. If you absolutely have to use interrupts, then set a flag inside the interrupt (a simple boolean variable), and use Serial inside your loo...
