WHAT IS ARDUINO IDE?

Arduino IDE (Integrated Development Environment) is a software application that provides a platform for writing, compiling, and uploading code to Arduino microcontroller boards. The purpose of Arduino IDE is to simplify the process of programming and interacting with Arduino boards, making it accessible to a wide range of users, including beginners and hobbyists.

STEP-BY-STEP GUIDELINES ARE GIVEN AS FOLLOWS:

Step 1: Download and Install Arduino IDE

1. Download the Arduino IDE:

 Go to "Arduino.cc." Select the appropriate version for your operating system (Windows, Mac, or Linux). Follow the instructions to download it.

2. Install Arduino IDE:

 When the download is complete, run the installer and follow the on-screen instructions to install the Arduino IDE.

3. Check the Device Manager (Windows) or System Report (Mac):

 Ensure that your computer recognizes the Arduino board. You should see the board listed under the "Ports" or "Other Devices" section.

Step 2: Open Arduino IDE 

 1. Launch Arduino IDE:

 Open the Arduino IDE that you installed in Step 1.

Step 3: Connect Your Arduino Board

 1. Connect Arduino Board:

 Connect your Arduino board, which you are going to use, with your computer using a USB cable.

 2. Select Your Board:

 Go to Tools > Board and select your specific Arduino board model (e.g., Arduino Uno, Arduino Mega).

 3. Select the Port:

 Go to Tools > Port and select the port to which your Arduino is connected.

Step 4: Select your first led blinking program

 1. Your basic LED code is here:

Write your Arduino code in the editor. If you're new to Arduino, you can start with a simple example like the Blink sketch, which makes an LED blink.

 2. Verify/Compile Your Code:

 Click the checkmark icon (✓) or go to Sketch > Verify/Compile to check for any errors in your code.

 3. Upload Your Code:

If the verification is successful, click the right-arrow icon (→) or go to Sketch > Upload to upload your code to the Arduino board.

 Now you can see the output on the Arduino Uno board.

Now you can see the actual output in serial monitor

Step 5: Monitor Serial Output (Optional)

 1. Open Serial Monitor:

 If your code uses the Serial Monitor, go to Tools > Serial Monitor. This is useful for debugging and seeing the output of your Arduino.

 2. Set Baud Rate:

 Ensure that the baud rate in the Serial Monitor matches the one specified in your code (Serial.begin(baud_rate)).
