VOICE MODULE AND RF LINK

INTERFACING

NAME: Easy VR Speech Recognition

Module v2.0

PROGRESS: Acquired and tested with

Arduino Uno

CHALLENGE: To directly interface the

module to MSP430 through UART

interface (powered at 3.3V - 5V)

NAME: Transmitter Receiver Schematic

SPECIFICATION: Zigbee protocol is

used to interface 315 MHz RF links to

MSP430

PROGRESS: Successful transmission

and reception of data wirelessly.

INTERFACING OF MOTORS AND

ULTRASONIC SENSORS

INTERFACING OF PUSH BUTTONS

AND LED LIGHTS

THINGS TO BE DONE

• Interfacing Voice recognition module to

MSP430 directly through UART.

• Acquiring the chassis and mounting all the

components on it for building the carcomponents on it for building the car

BACK UP PLAN

• To interface voice module with Arduino Uno

and connect the input output pins to the ports

of MSP430.
