Mobile Phone Flashing LED Module

A flashing LED module that responds to the radio signals from an adjacent (or near proximity) mobile phone. When the mobile phone in near proximity is receiving a call (or even just ringing), the in built pair of LEDs flash for around 20 seconds. The device can accomodate a further four surface mount LEDs. The module is ideal for use in novelty applications such as a device which can warn of an incoming call in environments where a ringer cannnot be used (such as in business meetings). The modules could also be used as an input for a project of your own design. Powered by 2xGP192 button cells (supplied).
