In this statement, any text can be put between the opening and closing quotes (” “) and it will be displayed in the serial monitor window. The second statement to run in the setup() function is Serial.println(“Hello, world!”), which sends the text Hello World out for display in the serial monitor window. The baud setting in the serial monitor window must match this value so that the evive and serial monitor window can communicate at the same speed. This statement sets up the speed of the serial port to 9600 baud. The statement Serial.begin(9600) is the first statement in the setup() function, so it is the first to run. In the Hello World sketch, statements in the setup() function will run first, from top to bottom. These statements are present in the setup function’s body. As the function does not return any value, it is initialised with the keyword void, meaning empty. void setup(): It is the function initialisation/declaration process of the function named setup().There are few things to notice in your sketch: This top-to-bottom execution of statements can be altered only by flow control statements.

In an Arduino sketch, program statements (individual lines of code) are executed, i.e. run from top to bottom.

If you get an error, please make sure that you have written the code correctly, connected evive and selected the appropriate COM port. The text that the program shows should be visible in the serial monitor window. Now open the Arduino IDE Serial Monitor Window to see the sketch run and print the text message.Click the Upload button to load the program to the Arduino.Connect your evive to your computer using a USB cable.

How to Run the Sketchįollow the steps below to run the sketch: Save your sketch by going to the File tab and then clicking on Save. Now, modify the code by initialising serial monitor and writing print statement inside setup() function. The statement to write on Serial Monitor is: Here 9600 is the baud rate at which you are communicating over USB with your device. To write in the serial monitor, you must first initialise serial monitor, you can do it with the help of the following statement: You can use it for debugging (finding errors in) Arduino programs when writing new programs. The digitalWrite() functions outputs a value on a pin.Serial communication is very useful for controlling electronic components or devices that are connected to (interfaced with) the Arduino board from the computer. As an output, it can drive an actuator like an LED. When configured as an input, a pin can detect the state of a sensor like a pushbutton this is discussed in a later tutorial. To use it, you pass it the number of the pin to configure and the constant INPUT or OUTPUT. The pinMode() function configures a pin as either an input or an output. These parameters are used by the pinMode() function to decide which pin and mode to set. For example, the line pinMode(ledPin, OUTPUT) calls the pinMode() function, passing it two parameters: ledPin and OUTPUT.

You can call a function that's already been defined (either in your sketch or as part of the Arduino language). Void setup ( ) is called the body of the function: what the function does. For example, here's the definition of the setup() function from the Blink example: FunctionsĪ function (otherwise known as a procedure or sub-routine) is a named piece of code that can be used from elsewhere in a sketch. There's more information in the Variables tutorial. For example, you could store the value read from an input into a variable. Often, however, the value of a variable will change while the sketch runs. The advantage of using a variable is that it's easier to move the LED to a different pin: you only need to edit the one line that assigns the initial value to the variable. In this case, the person writing the program could have chosen not to bother creating the ledPin variable and instead have simply written 13 everywhere they needed to specify a pin number. Every time the name ledPin appears in the code, its value will be retrieved. It's being used to indicate which Arduino pin the LED is connected to.

For example, the line from the Blink sketch above declares a variable with the name ledPin, the type int, and an initial value of 13. VariablesĪ variable is a place for storing a piece of data. The message 'LED connected to digital pin 13' is a comment. Int ledPin = 13 // LED connected to digital pin 13
