Arduino Workshop - Chapter Two - Using Serial Monitor

In this section, we'll be looking at using the serial port on the Arduino to communicate with a computer via USB.

why you don't use the auto format option after copying the sketch ?

i have been watching your workshop it is great i am having a problem when i try to manage my library or upload to my library it keep saying please can you help

[catiru]

my serial monitor says "not connected. select a board to connect automatically" how can i fix this??

[babyyoda]

Can't u use ctrl+t to do the indentation?

Ah Crap, I read that title as using Two Serial ports, since At Mega has two ports. can I shunt the data of one Serial.read() to print that out in the second Serial port and view that in the serial monitor?
It be helpful to he able to see the incoming data, while using it...

Can you tell me how can I erase the old data from my Arduino Uno board to upload a new one

[ildisonorevolesannita]

sorry for my English
does the the serial monitor function only when arduino is connected with the PC?

[hissenguinho]

For some reason my serial monitor doesn't make a new line :( do you know the reason?

int ledPin = 3;
int buttonPin = 2;
int potPin = A0;

void setup() {
// setup pin modes
pinMode(ledPin, OUTPUT);
pinMode(buttonPin, INPUT_PULLUP);
pinMode(potPin, INPUT);

// initialise serial port with baud rate of 9600
Serial.begin(9600);
}

void loop() {
// read the state of buttonPin and store it as buttonState (0 or 1)
int buttonState = digitalRead(buttonPin);

// read the value of the pot, divide it by 4, and store it as potValue
int potValue = analogRead(potPin);
int filteredPotValue = potValue / 4;

// turn led on with the value of potValue
analogWrite(ledPin, filteredPotValue);

// print the value of the button
Serial.print("Button: ");
Serial.print(buttonState);
Serial.print(" ");

// print the value of the pot
Serial.print("Pot: ");
Serial.print(potValue);
Serial.print(" ");

// print the value of the pot / 4 with a line return at the end
Serial.print("Pot/4: ");

}
