Bluetooth Controlled Lights

There are must be controller and client. Both must communicate via Bluetooth. Controller will be a common mobile phone with bluetooth enabled. Client will be a switcher for X LEDs powered by AA battery(ies). Depends on possibility of Bluetooth and latency there are two ways of switching: 1) On the fly: mobile phone via Bluetooth will continuously switch on and off individual LEDs in real time. 2) Mobile phone will fill the queue asynchronously and client will switch on and off individual LEDs by emptying the queue. Some chekpoints: • Find out how many LEDs is possible to control via Bluetooth in real time. The goal is around 50-100. • Find out how many LEDs is possible to keep light on max. 4x AA rechargeable batteries. • Find some modular Bluetooth box (e.g. [login to view URL]) • Design the protocol of communication for the best way of switching. • Create the smallest possible printed circuit board with all components. • Test it • Test it • Test it
