Arduino Workshop - Chapter Two - Using Serial Monitor 

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

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

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

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

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

Thanks for the upload

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 cc.arduino.contribuion.librery please can you help

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...

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

Very helpful.

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: "); Serial.println(filteredPotValue); }
