Figure out What You Want

The first step is to figure out what kind of smartwatch you want to make. There are a few different types of smartwatches, and each type has its own set of pros and cons.

Do you want a smartwatch that can make calls, send texts, and run apps? If so, you’ll need to use an Android Wear operating system.

Or do you want a fitness-focused smartwatch that tracks your steps, heart rate, and calories burned? If so, you might want to use the Garmin Connect IQ platform.

There are also hybrid smartwatches that combine the best features of both worlds. The Apple Watch, for example, is a hybrid smartwatch that runs apps and tracks fitness data.

Once you’ve decided on the type of smartwatch you want to make, it’s time to start collecting the necessary materials.

Step 2: Choosing the Right Components

Now that you know what type of smartwatch you want to make, it’s time to choose the right components. There are a few things to consider when choosing your components, such as:

Operating system

As mentioned before, there are a few different types of operating systems for smartwatches. You’ll need to choose an operating system that is compatible with the type of smartwatch you want to make.

Processor

The processor is the heart of your smartwatch. It handles all the data and instructions from the various sensors and applications. Make sure to choose a processor that is powerful enough to handle everything you want your smartwatch to do.

Display

The display is one of the most important components of your smartwatch. It needs to be large enough to see, but not so large that it drains the battery. You’ll also need to decide if you want a touchscreen display or a traditional watch face.

Battery

The battery is another important component to consider. You’ll need to choose a battery that is small enough to fit in your watch, but large enough to power everything for at least a day.

Sensors

Smartwatches use sensors to track data such as steps taken, heart rate, and calories burned. Choose sensors that are compatible with the operating system you’ve chosen and that will track the data you’re interested in.

Now that you know what components you need, it’s time to start putting your smartwatch together.

Step 3: Putting It All Together

Now that your smartwatch is up and running, it’s time to add the finishing touches. Start by customizing the watch face to your liking. You can also add wallpapers, ringtones, and fonts to personalize your device.

If you want to track fitness data, there are a number of apps available that can help you do just that. Many of these apps allow you to set goals, track progress, and compete with friends.

Finally, if you want to keep your smartwatch charged while on the go, there are a number of charging docks and cradles available. Choose one that fits your needs and lifestyle.

Congratulations! You’ve now built your very own smartwatch from scratch. Enjoy using your new device and don’t forget to show it off to your friends.

Compile Arduino Source for Watch and Upload

Now that you’ve put all the hardware together, it’s time to install the Arduino IDE and compile the source for your watch.

Installing the Arduino IDE is a simple process. Just head over to the Arduino website and download the latest version for your operating system. Once the download is finished, open the installer and follow the on-screen instructions.

Once the IDE is installed, launch it and navigate to the “File” menu. From there, select “Open” and choose the “smartwatch.ino” file from this repository. This will open up the source code for your smartwatch in the Arduino IDE.

Next, you’ll need to select your board type by going to the “Tools” menu and selecting “Board > Arduino Nano”. Finally, select the port that your watch is connected to by going to the “Tools” menu and choosing the correct port from the “Port” sub-menu.

Now that everything is set up, it’s time to compile and upload the source code to your watch. To do this, simply click on the “Upload” button in the Arduino IDE. The code will be compiled and then uploaded to your watch. Once it’s finished, you should see a message indicating that the upload was successful.

Install the Android app and download the source code

The next step is to install the Android app and download the source code. To do this, head over to the releases page and download the latest version of the app. Once the download is finished, launch the installer and follow the on-screen instructions.

Once the app is installed, open it and head over to the “Settings” screen. From there, select “Connect Watch” and follow the on-screen instructions to connect your watch to your phone.
