 In order for the Arduino to communicate with your computer it needs to have some kind of standard or
-protocol. Arduino can communicate over USB via what called "serial communication" or RS-232 This
+protocol. Arduino can communicate over USB via what called "serial communication" or RS-232/TTL. This
 allows us to send values (such as sensor readings) from the Arduino to the computer and back to the 
 Arduino (when a button is pressed, data from a web page, etc).

 You will need to open the Serial Monitor window in the Arduino IDE (located above) in order to

int buttonPin = 2;

void setup() {
  pinMode(buttonPin, INPUT);


    Serial.print("Button: ");  // a label for the data (useful when sending multiple readings)
    Serial.print(buttonState); // send the button's state
    Serial.print("\n");        // a 'newline' character so we get a line break (allows to see the data easier)
