Project Description Input & Outputs IR input Voice Commands Keypad 8051 Microprocessor Based System IR output Speaker LCD

Project Description Modes of Operation • Continuous Voice Recognition • Command Recognized – IR Transmit • Keypad Initiated Learn Mode – Learn Voice Command – Learn IR Command(s)

Project Description Sub-systems LCD (liquid crystal display) 8051 Microprocessor Keyboard IR Receiver Sensory Voice Direct II (Voice -recognition chip) Microphone IR Transmitter Speaker

Project Description Software Flowchart START Display: “Press Learn button or Speak ” no Voice Captured Recognized? no yes Learn Button Pressed? Retrieve corresponding IR command from External Memory yes Output IR command via IR transmitter interrupts Capture Voice Input save to Ext. memory Capture TTL IR pulses save to corresponding Ext. memory location

Project Description Datasheet • IR is TTL Level Controlled • Communication with Voice Direct II Board is Serial Bit Stream • Signal from microphone in m. V • IR receivers biased at 10 m. A • System programmed in assembly code

Project Description preliminary Lab work • Test IR equipment • Test IR commands IR Bit Stream IR Modulated Bit

Bill of Materials • Voice Direct II kit - RSC-300 - Speaker - Microphone • Micro Pac Evaluation Board • IR hardware - TSO-17(1, 3, 5) - Dependent on frequency (will have 34, 36, 40 KHz)
