Here is the chance to know and work with them. The assignment for this week is to redraw 'hello world' and add LED and push button on it. First I had to read the about the components and thier interaction then understanding the whole circuit. After I did that I read tutorials about EAGLE because we were told to use it for our assignment evenif,its the first time for me to interact with the software it didn't took too much time to work with it. I redraw the 'hello world' on the schematic then switch it on the board but the outcome here is so strange that I got the connections which I did on the schematic but it was too complex and hard to put it in the proper circuit diagram. After some trial I put the proper connection.</font></p> <img src="schematic.JPG" alt="shem" align="center"width="700"height="280"> <h3><p align="center">The schematic drawing</p></h3> <p align=justify><font color="white">The next step was to make ready of the board for milling machine so I saved the circuit from eagle board to photo image using monocrome that is two colors /black and white/ because the machine can understand it in such a way. The other thing I did was to cover free spaces/no any components and wires/with pad so that it will take no much time for the machine during production. My last step was to preserve what I did until I got the machines because the machines for our lab are still not coming. </font></p> <br><br> <img src="eagleonboard.JPG" alt="board" align="left"width="600"height="280"> <br><br><br> <br><br><br> <br><br><br> <br><br><br> <br> <br> <h3><p align="center">The circuit on the board</p></h3> <br> <img src="electronicsdesign.jpg" align="left"width="600"height="280"><br> <br><br> <br><br><br> <br><br><br> <br><br><br> <br> <br> <h3><p align="center">Ready for the production</p></h3> <br><br><br> <p align=justify><font color="white">. </font></p> <a href="http://www.facebook.com/"><img src="facebook.jpg" align="right"width="30" height="30"> </a> <a href="http://www.youtube.com/"><img src="youtube.jpg" align="right"width="30" height="30"> </a> <a href="http://www.twitter.com/"><img src="twitter.jpg" align="right"width="30" height="30"> </a></td> </tr> <tr> <td style="background-color:#ff0000;text-align:center;"> Copyright 2012 habtamu. g</td> </tr> </table> </body> </html>
