Objective

To learn how to add external libraries to Arduino IDE and configure the IDE for programming a board.

Part A: Adding Libraries in Arduino IDE

There are three methods to add libraries:

---

Method 1: Using the Library Manager (Recommended)

1. Open Arduino IDE.
2. Go to Sketch > Include Library > Manage Libraries... (or press Ctrl + Shift + I).
3. The Library Manager window opens.
4. In the search box, type the name of the library (e.g., DHT sensor library).
5. Select the desired library from the list.
6. Click the "Install" button.
7. Once installed, the library appears in Sketch > Include Library menu.

---

Method 2: Installing a .zip Library

1. Download the library as a .zip file from GitHub or another source.
2. In Arduino IDE, go to Sketch > Include Library > Add .ZIP Library...
3. Browse to the downloaded .zip file and click "Open".
4. The library is installed and available immediately.

Method 3: Manual Installation

1. Download and extract the library folder.
2. Copy the extracted folder to the Arduino libraries directory:

• Windows: C:\Users\<YourName>\Documents\Arduino\libraries\
• macOS/Linux: ~/Documents/Arduino/libraries/

1. Restart the Arduino IDE.
2. The library will now appear in Sketch > Include Library.

Part B: Arduino IDE Setup for Programming

Step 1: Connect the Arduino Board

1. Connect the Arduino board to the computer using a USB cable.

Step 2: Select the Correct Board

1. Go to Tools > Board > Arduino AVR Boards.
2. Select your board (e.g., Arduino Uno).

Step 3: Select the Correct Port

1. Go to Tools > Port.
2. Select the COM port that corresponds to your Arduino (e.g., COM3 on Windows or /dev/ttyUSB0 on Linux).

Step 4: Verify a Test Sketch

1. Go to File > Examples > 01.Basics > Blink.
2. Click the Verify (✓) button to compile.
3. Click the Upload (→) button to upload to the board.
4. The onboard LED should start blinking — confirming the setup is correct.

Step 5: Use Serial Monitor

1. Go to Tools > Serial Monitor (or press Ctrl + Shift + M).
2. Set the baud rate to match Serial.begin(9600) in your code.
3. Use it to print debug messages from your Arduino program.

Result

Libraries have been successfully added and Arduino IDE has been configured for programming.
