How to Display Line Numbers in the Arduino IDE for Windows 1.8.5

================================================================================

The latest version of the popular Integrated Development Environment (IDE) for creating sketches and projects based on microcontrollers from Arduino offers several new features that can significantly improve your development experience.

One such feature is the ability to display line numbers alongside each code block within an open sketch file in real-time as you edit. This article will walk you through a step-by-step guide on how to enable this useful functionality using the latest version of the Arduino IDE for Windows 1.8.5.

Prerequisites

---------

Before proceeding, ensure that your system meets these requirements:

* You are running an operating system compatible with Windows (Windows XP or later).

* The latest version of Java Development Kit (JDK) is installed on your computer.

* Arduino IDE for Windows 1.8.5 has been downloaded and extracted to a suitable location, preferably the 'C:\Program Files' directory.

Step-by-Step Instructions

----------------------

### Step 1: Launching the Arduino IDE

Double-click on the 'Arduino' icon located in either your Start menu (for versions prior to Windows 10) or within the newly created 'Start > All Programs > Arduino' folder. Alternatively, you can directly open it by navigating through the following path using File Explorer:

```c

C:\Program Files\arduino-1.8.5/Arduino.exe

```

### Step 2: Configuring Editor Preferences

Upon launching the IDE for the first time or if this feature has been disabled previously, a new window titled 'Editor' will appear with several options listed on its left-hand side panel.

From the provided list, double-click on either 'Appearance & Behavior -> Editor-> Line Numbers' or simply type 'line numbers' in the search bar at the top-right corner and press Enter to navigate directly to this option.

### Step Show Line Numbers

In the newly opened dialog box, check both boxes alongside 'Show line numbers' under the corresponding section. You can now either choose whether you want to display line numbers on a per-tab basis by selecting from the dropdown list below or opt for global settings using the respective checkboxes located at its bottom-right corner.

### Step 4: Save and Apply Changes

Once done, click OK to apply these changes system-wide (or only within the current IDE window depending upon your previous selection). To persistently enable this feature across future sessions of Arduino IDE:

1. Go back to 'File > Preferences...'

You are now ready to begin coding with line numbers enabled for each new or existing sketch in the latest version of the popular microcontroller development environment.

In conclusion, displaying line numbers alongside your code can significantly enhance both understanding and debugging processes when working on complex projects using languages such as C++ within integrated development environments like Arduino IDE. By following these simple steps outlined above, you'll be able to easily access this useful feature in no time while developing innovative solutions with ease.
