Custom Firmware Development for Diy Smartwatch: Time & Gesture-Activated Video

The client requires a skilled freelancer to develop custom firmware for a DIY smartwatch, such as a LILYGo or similar platform. The primary objective is to streamline the device's functionality to only two specific features: displaying the current time and initiating video playback when the user performs a wrist-turning gesture (as if checking the time). All other pre-existing or potential functions of the smartwatch must be disabled or removed to ensure a minimalist and focused user experience. The freelancer will be responsible for understanding the chosen smartwatch's hardware capabilities, developing the necessary code for time display, implementing reliable wrist-turn detection for video activation, and ensuring all non-essential features are eliminated. Experience with embedded systems, microcontroller programming, and sensor integration is highly valued.
