If you own a smartphone, chances are you’ve interacted with a beacon before. These tiny devices have become increasingly popular over the years, thanks to their ability to communicate with smartphones and other devices via Bluetooth signals. Their primary purpose is to transmit location data and other relevant information to nearby devices.

In this article, we’ll take a deep dive into how to make a beacon from scratch. We’ll show you the different types of beacons available, give you step-by-step instructions on how to make your own beacon, and teach you how to program and configure it for various purposes. So, let’s get started!

How to Make a Beacon

To get started with making a beacon, you’ll need a few essential materials:

  • A Raspberry Pi or Arduino
  • A Bluetooth module
  • A 9V battery
  • A few jumper wires

You can find these materials online or at your local electronics store. Once you have all these materials, you can begin building your beacon.

Here’s a quick step-by-step guide:

  1. Attach the Bluetooth module to your Raspberry Pi or Arduino.
  2. Connect the 9V battery to the Bluetooth module.
  3. Use the jumper wires to connect the Bluetooth module to the Raspberry Pi or Arduino.
  4. Write a simple program to make the Bluetooth module transmit a signal.
  5. Upload the program to the Raspberry Pi or Arduino.
  6. Power on your beacon and test it out by using a nearby device with Bluetooth enabled to detect the signal.

If you’re a visual learner, you can find plenty of detailed tutorials and helpful step-by-step guides online, with illustrations to help you build your own beacon.

Different Types of Beacons

So, what are the different types of beacons available? There are a few options to choose from:

  • iBeacon: This is one of the most popular types of beacons available and is typically used in iOS devices. iBeacons use Bluetooth Low Energy (BLE) technology to transmit data.
  • Eddystone: Developed by Google, Eddystone is an open-source beacon format that can be used with both Android and iOS devices.
  • AltBeacon: AltBeacon is a more flexible beacon format that can be used across all operating systems, including iOS and Android.

Each type of beacon has its own set of features and characteristics. You can choose the one that best suits your needs based on the requirements of your project.

Customize Your Beacon

If you want to make your beacon stand out, there are many ways you can customize it. You can add some eye-catching colors or even create your own unique pattern to distinguish it from other beacons.

But customization doesn’t stop there. You can also configure your beacon to broadcast different types of data based on your preferences. For instance, you can use it to transmit special offers or discounts to nearby shoppers, or even track customer behavior patterns for analytics purposes.

Applications of Beacons

Beacons have many different applications across various industries. Let’s take a look at a few examples:

  • Retail: Retailers can use beacons to track customer behavior patterns and preferences, send personalized offers, and enhance the in-store shopping experience.
  • Healthcare: Hospitals can use beacons to track the location of patients, medical equipment, and personnel.
  • Transportation: Airports and train stations can use beacons to notify passengers about changes in departure times, gate numbers, and other relevant information.

As you can see, beacons have the potential to improve customer experience and engagement in many different industries.

Technical Aspects of a Beacon’s Operation

Beacons work by transmitting Bluetooth signals at regular intervals. Nearby devices with Bluetooth enabled can detect these signals and perform specific actions based on the broadcast data. For instance, a retail store beacon can transmit special offers to nearby shoppers.

However, there are some technical aspects worth considering when working with beacons. For instance, a beacon’s battery life can significantly affect its performance. You’ll need to choose a battery that can power your beacon for the intended runtime. Additionally, you will need to optimize the transmission range and frequency of your beacon to ensure maximum performance.

Programming and Configuring a Beacon

Once you’ve built your beacon, you’ll need to program it to perform specific actions based on your project requirements. You can use various programming languages such as C++, Python, or Ruby to create your programs and upload them to your beacon.

You can also use various tools like Github or Firebase to manage and deploy your beacon’s programming. However, it’s worth noting that programming and configuring a beacon can be challenging, especially if you’re a beginner. That’s why it’s always helpful to follow step-by-step tutorials or reach out to online communities for guidance.

Integrating Beacons into Other Tech Advances

Beacons can be integrated into other tech advances like IoT, AI, and big data to enhance their performance and provide valuable insights. For instance, beacons can work efficiently with IoT devices to collect and analyze data, and AI can use this data to make predictions and optimize performance. Additionally, beacons can provide insights that can help smart cities become more efficient and sustainable.

Many case studies demonstrate the effectiveness of integrating beacons into other tech advances. For example, in New York City, beacons have been installed along high-traffic areas to assist in emergency responses.


In conclusion, beacons are tiny devices with a significant impact on various industries. Making a beacon is an interesting project that can help you learn more about programming and electronics. By following this beginner’s guide, you can build your own beacon, customize it, and program it for various purposes.

Beacons also have many applications and can be integrated into other tech advances like AI, IoT, and big data. As we continue to witness the growth of smart cities and other tech advances, beacons will undoubtedly play a more significant role in our lives.
