Smart cool bracelet can switch any mode, and it is also a watch. Will this watch be flashy?

No, dany boon Side, a designer of crooked fruit, has launched a smart jewelry bracelet. Gray is very cool-it's a bracelet, but it's more like a mobile phone worn on your wrist, except that the screen is replaced by an organic light-emitting diode flexible display. And these colorful patterns on the screen, just like the dynamic wallpaper in the mobile phone, are very beautiful. Of course, it is more than just an ornament. Click to display the time and weather. In addition, it can also notify and access ins, Facebook and so on. Look at the circle of friends and give others a compliment. Unfortunately, it can't make a phone call, otherwise this bracelet can completely replace the mobile phone!

The completed Arduino project can be downloaded on GitHub. Don't rush to compile after downloading, you need to configure the development environment first. Installation of graphics driver: firstly, the graphics processing libraries Adafruit_SSD 1306 and Adafruit-GFX need to be installed to display images on the OLED. (In some development environments, Adafruit library will conflict with Robot_xxx library; If this happens, back up the Robot_xxx library and delete it from the library folder. )

After installing Android software, check whether the system grants it the right to read notifications. Next, turn on the Bluetooth of the mobile phone and pair the Android phone with Arduino's Bluetooth. Then select the connected Arduino in RetroWatch software, and "Connected" on the interface means that the connection is successful. Click the menu, select DatatransfertoWatch, and then the device will use Bluetooth to transmit time and information to the smart watch.

Because the hardware performance of the watch is limited, many functions need to be realized through Android applications. The main function of the watch itself is display. In the Android application, you can set the types of pushable messages (only supporting English character display) and status notifications (battery power and signal strength of the mobile phone, etc.). ), and you can also push the subscribed RSS in the application (you can subscribe to the weather RSS to display the weather on your watch). Updates are synchronized every 30 minutes.
