Project Definition
Wearable technologies are becoming increasingly important in today’s world. Among them, smartwatches are the most widely accepted technology among consumers.
Within the scope of the project, I developed a smartwatch and an associated Android application that communicates with it. The smartwatch is designed as an embedded system without a full-fledged operating system. In addition to essential clock functions such as time, alarm, and stopwatch, the smartwatch will have features such as receiving notifications, handling calls, and controlling the media player on the phone. The touchscreen-operated watch will also include an accelerometer, a buzzer for alarm sounds, and a motor for vibration.
On the mobile side, a mobile application can respond to requests and messages sent by the smartwatch via Bluetooth. The application allows users to set alarms on the smartwatch and will manage background services such as notifications, calls, and media controls using Android services.
