today – the Arduino adventure begins

-old RC cars – no remote needed.  Note that the car will NOT work again after we hack them.  They will never work.
-small speakers – like from a radio or one of those audio greeting cards


1 Arduino board
1 breadboard
1 USB cable
1 resistor
2 jumper wires

Part 1 BLINK

  1. attach the Arduino to the USB cable
  2. attach the cable to the USB port on the back of the computer
  3. search your computer for Arduino
  4. from the Arduino program click on File, Examples, Basics and choose Blink
  5. click on the ARROW at the top menu bar. Screen Shot 2015-10-22 at 12.55.34 PM
    This compiles your sketch (program) and uploads it to the Arduino.
  6. IF IT WORKS the small orange LED on the board will blink.  Now go back into the sketch and change the delay(1000) value to a smaller or larger number.  Upload again.
  7. IF IT DOESN’T WORK – relax.  Click on Tools, Port and choose the lowest option on the drop down menu.


  1. unplug your Arduino from the USB cable.
  2. grab an LED
  3. insert the long leg (wire) of the LED into the pin labeled 13.
  4. insert the short leg into the ping labeled GND (ground).
  5. plug the USB cable back in.  What happens?


  1. grab your breadboard and duplicate this circuit BELOW.  Click to enlarge the image.  We will do this together on the big screen as well.
  2. once you reconnect your Arduino the red LED should start blinking along with the small orange LED on the Arduino.
  3. add two more LEDs like this.redyellowgreenLED_bb
  4. how can you get the new LEDs to blink like the red LED?  We will explore this together by modifying the Blink sketch.

Part 4: color changing RGB LED

Ok so now try one on your own.  Grab an RGB LED and follow this short tutorial.  You will recycle your wires and resistors for this project.

QR Code to Portfolio

October 20, 2015 at 9:00 am | Posted in tech | Leave a comment

In this project you will create a QR code and marketing piece that will link to your Computer Graphics Digital Portfolio.   These pieces will be displayed in the Drake hallways.2014sampleqrportfolio

the BIG steps
1. make your Digital Portfolio PUBLIC
2. grab the URL from your portfolio and create the QR code
3. create a page in Photoshop to layout your marketing piece

Make your Digital Portfolio PUBLIC

1. remove your last name
2. make it public – here’s how

Create the QR code
1. use the URL for your Portfolio and go to kaywa.com
2. create the QR code and save it
3. open the QR and customize it in Photoshop.  Consider how you can change the code to make it interesting yet still work.
4. test test test and then save it

The marketing piece
1. create an 11 inch wide, 8.5 inch high image – 180 dpi
2. place your MODIFIED QR code on your image
3. show your viewer that they have to click the code to view your portfolio
4. place at least two images – no more than five – of your graphic works on the image
5. include your FIRST name and “created in Computer Graphics”.
6. save it.
7. print it.
