A flashing LED module that responds to the radio signals from adjacent mobile phones.

With the current interest in mobile phones, the module provides an excellent basis for a range of product design exercises
The module responds to either incoming or outgoing phone signals by flashing a 20 second light sequence through 2 LEDs
Up to 4 additional surface mount LEDs can be added to the circuit. Red 72-8350, Green 72-8360, Yellow 72-8365
The module can also be used as an input module for other circuits
Built-in antenna
Powered by 2x L736 (GP192) button cells (supplied)
For replacement cells, see Batteries section
Effective distance from the phone to the module varies greatly, dependent on the type of phone and the environment, but could be up to 0.5m
The notes provide students with essential background information to help develop a range of product design ideas and look at current mobile phone technology and how the style of mobile phones has changed
Suitable for Key Stages 2, 3 & 4 (ages 7 to 16)
