This security system will walk through three levels, starting with unique pin code pressed on the touch pad. Next, the user is asked to tap his or her ID card towards the RFID reader. The third level is the voice recognition of the user's unique voice pattern. However, this feature is not implemented for now. After all levels are cleared, the user will have access to his or her classified information.

Wiring
Here are the connections for the demo code: mbed Touch Keypad
Gnd => Gnd
p9 => SDA
p10 => SCL
p26 => IRQ
Vout(3.3V) => Vcc
The I2C pullups on SDA and SCL are not provided on the touch keypad board, so add two 4.7K ohm pullups to 3.3V to the circuit. The other breakout board with the MPR121 only, has the pullups on the board.

Wire connections from EasyVR to mbed

VU => Vcc => red
RX(14) => ETX => white
