4. Objective 4 To make a working Java program 4 Put it on the internet using an Apache program 4 Control electronic devices through the internet

5. Description of project 4 To create a Java program 4 Compile the Java program translate so the computer understands 4 Make the compiled program an Apache program- The bridge between Java and the internet 4 Format to an HTML 4 Post on the web

6. Progress Report 4 We finished the circuitry for the parallel port interface. 4 We finished the poster board and research paper. 4 We took out the bugs in our program.

7. What is a Parallel Port? 4 Data Transfers –Data out –Control out –Status in

8. Parts of the Port 4 8 output pins accessed via the DATA Port 4 5 input pins (one inverted) accessed via the STATUS Port 4 4 output pins (three inverted) accessed via the CONTROL Port 4 The remaining 8 pins are grounded

9. Parts of the port (continued…)

10. The Parallel Process 4 Information transfer form computer to the parallel port. 4 Data transfer out to robotic device (printer) 4 Printer receives signal and then sends a reply signal.

11. Port Replies 4 These reply signals are made up of the following Pin’s –Acknowledge -10 –Busy -11 –Paper End -12 –Select In -13 –Auto Feed - 14 –Error -15 –Initialize - 16 –Select -17
