**Tutorial 3: Setting up Arduino Uno with Arduino IDE**
### Step 1: Install Arduino IDE
To start, you need to download and install the Arduino IDE on your computer. You can download the latest version from the official Arduino website. Once downloaded, follow the installation instructions to install the IDE on your computer.
### Step 2: Connect Arduino Uno to Computer
Connect the Arduino Uno to your computer using a USB cable. Make sure the cable is properly connected to both the Arduino board and the computer.
### Step 3: Install USB Driver
The Arduino Uno uses a ATmega16U2 or ATmega8U2 USB-to-serial converter chip. You may need to install a driver for this chip. You can download the driver from the official Arduino website or from the manufacturer's website. Follow the installation instructions to install the driver on your computer.
### Step 4: Select Board
Open the Arduino IDE and go to **Tools** > **Board**. Select "Arduino Uno" from the list of available boards.
### Step 5: Write and Upload Blink Program
Create a new project in the Arduino IDE by going to **File** > **New**. Copy and paste the following code into the editor:
```c
const int ledPin = 13;
void setup() {
pinMode(ledPin, OUTPUT);
}
void loop() {
digitalWrite(ledPin, HIGH);
delay(1000);
digitalWrite(ledPin, LOW);
delay(1000);
}
```
This code will blink the built-in LED on the Arduino Uno. Select the correct port from the **Tools** menu, then click **Upload** to upload the code to the Arduino Uno.
### Step 6: Verify Blink Program
Once the code is uploaded, the built-in LED on the Arduino Uno should start blinking. If it doesn't, check the connections and make sure the code is correct.
