SECTION 1: Display Circuit
- First you’ll need to wire together all of the pixels. Attach 5V, ground, and a line for the pin through each pixel as shown, leaving about [dimension] of wire in between each one.
- Connect the end of the pixel strand to 5V and ground on the AC adapter as well as ground on the Arduino UNO. Connect the middle wire to pin 2.
- Test that the pixels light up using the Arduino sample code [name].
- If it doesn’t work, here are some troubleshooting tips:
- Next you’ll need to hook up one of the xbee modules. Place the xbee module on the xbee adapter, then attach the assembly to your breadboard.
- Reference the above circuit diagram to connect the xbee adapter pins on the breadboard to the Arduino UNO.
- That’s it for this circuit – next, constructing the display housing.
SECTION 2: Display Construction
- Cut out hole in [dimension] wooden back panel using laser cutter or jig saw. This is where the power supplies will attach to. See [file name] for location and dimensions.
- Use wood glue to attach the sides ([dimension]) of box to the back panel. Then use [length] wood screws to secure the top and bottom pieces ([dimension]).
- Mount the Arduino UNO and circuit to the inside of the base, as shown.
- Next it’s time to assemble the LED housing. Start by cutting out the LED holes in the cardboard back panel. It doesn’t need to be exact, but aim to place holes at [dimension] increments, as shown above.
- Assembly the cardboard box following the schematic above.
- Mount the pixels on the cardboard with [material].
- Take the [dimension] black cardstock and cutout [dimension] rectangles and the through holes at the corners.
- On the back side of the cardstock, glue on the [transparent material].
- Glue cardboard box onto the black cardstock, being sure to align the rectangular pockets for the LEDs with the rectangular cutours on the black cardstock.
- Cutout [dimension] holes into the acrylic piece.
- Screw the acrylic and cardboard assembly into the front face of the wooden box with [dimension] wood screws.
- Great! You’ve finished the display. Now it’s time to make the band.
SECTION 3: Band Circuit
- Start by attaching your other xbee module to the xbee adapter, as you did for the display module.
- This can be wired the your Flora as shown in the circuit diagram above.
- Next you’ll need to hook up the accelerometer to the Flora, connecting 3V, SDA, SCL, and GND.
- Solder the leads of the lipoly battery to the Flora.
- You’ll want to test that the accelerometer is functioning properly with [name] example code.
- At this time you can also test that the xbee modules are functioning with [name] example code.
- If all of this is in order, it’s time to build your band!
SECTION 4: Band Construction
- You can 3D print the housing for your band’s electronics using this STL file:
- Create the band by sewing [material] through the loops of the 3D printed housing as shown.
- Place the electronics in their respective spots, then cover them up with the 3D printed lid.
SECTION 5: Finishing and Testing
- Plug in the 5V adapter for the LEDs and the USB charger for the Arduino UNO to the back of the display.
- Load [name] code to Arduino UNO and [name] code to Flora.
- Start drawing! The code is set to increase one bar every 10 minutes of drawing. You can adjust this setting in the part of the code labeled [name].
