Arduino Workshop - Project 05: Push-On, Push-Off - Part 2

Hardware Required:
  • Arduino Uno board
  • LED (x2)
  • 330 ohm (x2), 10 K ohm resistors
  • Pushbutton switch (N.O.)
  • jumper wires

    Hardware Required

Schematic:

Project Steps:


  1. Assemble an LED and pushbutton, following the directions for project 4.
    Add a second LED:
  2. Insert a second LED in the breadboard
  3. Connect a wire between the ground and the short pin of the second LED
  4. Connect a 330 ohm resistor between the D12 on the Arduino and the long-leg of the LED
    Change the program to turn LED2 on when LED1 is off, etc..
    • Save a copy of the Project4 code as a Project4b (file, save-as, enter new name)
    • Change all of the "LED" variables to "LED1"
    • Copy each line containing "LED1" and paste as a new line immediately following it.
    • Change "LED1" in each of the duplicate lines to "LED2", for example:
      const int LED1 = 13;
      const int LED2 = 13;
    • Change the Digital Output used for LED2 to 12 (const int LED2 = 12;)
    • Change the lines that turn LED2 on and off to the opposite of what LED1 has:
      digitalWrite(LED1, HIGH);
      digitalWrite(LED2, LOW);
    • Verify your code and upload to the Arduino.

Tech News: What's new in Microsoft Office 2013?

Office 2013, the next edition of Microsoft’s flagship productivity suite, is available for business customers but won’t go on sale to consumers until the first quarter of 2013.

We got a look at it and here’s what is new in Microsoft Office 2013.

  1. Office 2013 has undergone some drastic new changes featuring a clean new interface, and is more accessible that any previous version of Office.

  2. The first thing you will notice in Office 2013 is the new modern interface. It still has the ribbon on the top with all of the toolbars just like Office 2007 and Office 2010.

  3. In the top right corner you will notice that you can sign in using a Microsoft account allowing you to access your Office documents from any Windows computer, smart phone, or tablet.

  4. Another way Office is more accessible is the added feature of saving your documents to Microsoft's cloud storage SkyDrive, allowing you to easily share documents and access them from anywhere.

  5. Making a new document has been made even easier with the expanded templates in Office 2013.

  6. Saving and opening files has been streamlined as well. Your most used folders will show up when saving and opening documents and you can even pin specific folders to the list.

  7. Sharing your document for collaboration has been simplified. Office 2013 allows you to invite people to view your document, email your document, present your document using Office Presentation Service, or Publish the document as a blog post.

  8. These are just a few general new features across the Office 2013 suite. Each individual Office program also has their own new features.


What do you think? Will you get Office 2013?
