How To Make Smart Glasses DIY at Home

Introduction

In this tutorial, we will guide you through the process of creating your very own smart glasses at home using accessible components like an Arduino Nano, a Bluetooth module, and an OLED display. These smart glasses will allow you to view notifications and the time directly in your line of sight, bringing the Internet of Things (IoT) technology into your everyday life.

Step 1: Gather Your Materials

Before starting the project, ensure you have the following components:

• 0.96 inch OLED display (available here)
• HC-05 Bluetooth module (available here)
• Arduino Nano (available here)
• Wires and connectors
• Soldering tools (if necessary)
• A pair of glasses or a frame to attach the components

Practical Tip

Make sure to purchase quality components to ensure better performance and longevity of your smart glasses.

Step 2: Set Up the Arduino Environment

1. Download and Install Arduino IDE

   • Visit the Arduino website to download the latest version of the Arduino IDE.
   • Install the software on your computer.

2. Connect Arduino Nano

   • Use a USB cable to connect your Arduino Nano to your computer.
   • Open the Arduino IDE and select the appropriate board and port from the tools menu.

Step 3: Connect the Components

1. Wiring the OLED Display

   • Connect the VCC pin of the OLED to the 5V pin on the Arduino.
   • Connect the GND pin to the GND pin on the Arduino.
   • Connect the SDA pin to the A4 pin on the Arduino.
   • Connect the SCL pin to the A5 pin on the Arduino.

2. Wiring the Bluetooth Module

   • Connect the VCC pin of the HC-05 to the 5V pin on the Arduino.
   • Connect the GND pin to the GND pin on the Arduino.
   • Connect the TX pin of the HC-05 to the RX pin on the Arduino (D0).
   • Connect the RX pin of the HC-05 to the TX pin on the Arduino (D1).

Common Pitfalls to Avoid

• Double-check wiring connections to prevent short circuits.
• Ensure the correct orientation of the OLED display.

Step 4: Upload the Code

1. Download the Code

   • Access the code from the GitHub repository here.

2. Upload the Code to Arduino

   • Open the downloaded code in the Arduino IDE.
   • Click on the upload button to transfer the code to the Arduino Nano.

3. Testing the Setup

   • Once the code is uploaded, disconnect the Arduino from the USB and power it using a battery or an alternative power source.
   • Ensure that the OLED screen lights up and displays the expected information.

Step 5: Assemble the Smart Glasses

1. Attach Components to the Frame

   • Securely attach the OLED display and Bluetooth module to your glasses frame.
   • Use hot glue or adhesive tape to ensure everything stays in place.

2. Finalizing the Design

   • Make sure that the display is positioned in a way that it’s easily visible while wearing the glasses.
   • Check that all components are well secured to avoid damage during use.
