arduino uno hello world

To create a "Hello World" program using an Arduino Uno, follow these steps:

Step 1: Set up the Arduino IDE - Download and install the Arduino IDE (Integrated Development Environment) from the official Arduino website. - Launch the Arduino IDE after installation.

Step 2: Connect the Arduino Uno - Connect the Arduino Uno board to your computer using a USB cable. - Ensure that the board is recognized by your computer and the appropriate drivers are installed.

Step 3: Open a new sketch - Click on "File" in the Arduino IDE menu and select "New" to open a new sketch.

Step 4: Write the code - In the Arduino IDE, write the following code:

void setup() {
  // Setup code goes here (optional)
}

void loop() {
  // Main code goes here
  Serial.begin(9600);
  Serial.println("Hello, World!");
  delay(1000);
}

Step 5: Compile the code - Click on the checkmark icon (or select "Sketch" > "Verify/Compile") to compile the code. - If there are no errors, the code will be successfully compiled.

Step 6: Upload the code - Click on the right arrow icon (or select "Sketch" > "Upload") to upload the code to the Arduino Uno. - The Arduino IDE will compile the code again and then upload it to the board. - Wait for the upload process to complete.

Step 7: Open the Serial Monitor - Click on the magnifying glass icon (or select "Tools" > "Serial Monitor") to open the Serial Monitor. - Set the baud rate to 9600 (or the same as in the code). - You should see the "Hello, World!" message being printed repeatedly.

That's it! You have successfully created a "Hello World" program on an Arduino Uno using the Arduino IDE.
