VIP Badge - New Orleans Maker Faire 2018

Badge code and instructions for the 2018 NOLA Mini Maker Faire VIP Badge Kit

You can purchase your VIP tickets for the 2017 New Orleans Mini Maker Faire at: https://www.eventbrite.com/e/new-orleans-mini-maker-faire-2018-tickets-39528726485

This kit is included with the purchase of the VIP ticket. One kit per VIP ticket.

Be creative! The components chosen for this design were picked with the intention that you would want to customize your badge to make it your own. Paint it, stain it, change the program, add more components, etc.

Components

The following components are included in the 2018 VIP Badge Kit:

• Arduino Pro Micro with ATmega32U4 5V/16MHz
• White 128X64 0.96 inch OLED with SPI
• 3 x AAA Battery Pack
• Blue 5mm LED
• 1k Ohm Resistor, 1/4 W, 5% (qty. 3)
• Surface mount switch (qty. 2)
• Piezo speaker
• Custom designed PCB
• Laser cut top piece
• Bots and nuts (qty. 2)
• Neck lanyard

What you'll need

Gather these tools before starting on your build and it will go much smoother! With the custom designed PCB, there's less wires to get in the way and hooking everything help will be easy.

• Soldering iron and solder
• Hot glue and gun
• Flush cut wire cutters and/or wire stripper
• Micro USB cable
• Computer with the Arduino IDE loaded
• (optional) Blue tack to help hold pieces while soldering

Tips for Building Your Badge

Please read and review before starting your build.

Step 1: Attach the LED, speaker, resistors and switches

• Pay attention to the positive and negative leads on the LED and speaker components
• On the LED, the longer lead is positive, the shorter lead negative
• The leads on the speaker will need to be bent in order to match up to the holes
• The resistors can be mounted in either direction
• The switches should mount with the pins exited the left and right sides

Step 2: Attach the OLED and Arduino

• Use blue tack or helping hands to help mount the included header pins
• The longer side of the pins should go through the PCB. These can be soldered to on the reverse side for expansion
• Once the headers have been soldered, you can solder on the OLED and Arduino
• The OLED screen will "float" above the PCB. You can use some hot glue under the OLED to help secure it if needed

Step 3: Attach battery pack

• Use hot glue to mount the battery pack with the switch facing out.
• Trim the red and black leads
• Your red lead will be positive, the black lead is negative

Step 4: Attach top piece and lanyard

• Use the supplied bolts and nuts to secure the top piece
• Be sure to remove any backing paper from the top piece
• Attach the lanyard and we'll see you at the Faire!

Compiling the Code

Step 1: Install required libraries

There are two libraries required to make the LCD work. You'll need to download each and stores them in your Arduino library so the compiler can find them when you compile the code.

• Download: https://github.com/adafruit/Adafruit-GFX-Library
• Click the green button for "Clone or download" and choose "Download ZIP"
• Once you extract the ZIP file, you'll want to place the entire unzipped folder in your "libraries" folder which is in your Sketchbook location
• In the Arduino IDE, you can find your Sketchbook location by going to File -> Preferences (on Windows) or Arduino -> Preferences (on Mac)
• Follow these same steps for: https://github.com/adafruit/Adafruit_SSD1306

Step 2: Define correct LCD in SSD1306 library

• Open the file "Adafruit_SSD1306.h" in the SSD1306 library folder you just placed
• Pro tip: On Windows, use Wordpad and turn on word wrap, on Mac, open the file with TextEdit
• You want to make sure the line #define SSD1306_128_64 is uncommented and the other two options are commented (that means they have the two forward slashes in front)
• Looks like (around line 64/65):

     #define SSD1306_128_64
//   #define SSD1306_128_32
//   #define SSD1306_96_16

• This is because the 128x64 LCD is the one included in the kit
• Save the file

Step 3: Download this source code

• Just like the two libraries before, click the green button and select "Download ZIP"
• Once extracted, you can move the "badgeCode" folder to your Sketchbook folder

Step 4: Modify your name and compile

• On line 41, change the definition of "MYNAME" to your own name
• Under Tools -> Board, select "Genuino Micro"
• Under Tools -> Port, select the USB/Serial port that shows up when you plug in the Arduino
• Click the Checkmark to compile, click the Right arrow button to upload your code to your Arduino
