Very simple but smart doorbell
This smart doorbell will feature a simple button, a proximity sensor and prominent rgb led indicator that changes color as a visitor approaches. It is supposed to have at least 3 parts, the fixed wall mount, removable rechargable battery and the actual doorbell. The three components will be held together magnetically. The goal is to have a simple, elegant and functional design that will have minimal manufacturing cost. It should focus on simplicity and affordability. Please see attached image for more info.
Evaluation will be based on it's simplicity, originality and overall look and feel.
