# Green Goblin Pumpkin CPB Ornament
## Overview
https://youtu.be/nAJu8YdBalw
Build an LED ornament inspired by Spiderman's Green goblin!
Use the built-in LEDs on the Circuit Playground Bluefruit and an additional NeoPixel ring on the back to illuminate on both sides of the ornament!
The 3D printed shell fits over our 6cm DIY ornament with a printed mount to hold the Circuit Playground Bluefruit and 16 NeoPixel ring.
Use CircuitPython to easy edit the color, animations or even motion or add sounds with the build-in speaker on the Circuit Playground Bluefruit!
## Rechargeable
Easily power up the Ornament with an Adafruit Micro-Lipo Charger!
Simply plug it via USB cable into a USB port and our lipo rechargeable battery into the JST plug on the other end. There are two LEDs - one red and one green. While charging, the red LED is lit. When the battery is fully charged and ready for use, the green LED turns on. Seriously, it could not get more easy!
## Parts
The Circuit Playground Bluefruit is powered by a 500mah battery.
Components snap fit on to a 3D printed mount. The mount press fits into a 6cm plastic ornament. Printed outer shells attach to each half of the ornament.

## Circuit Diagram
The diagram below provides a visual reference for wiring of the components. This diagram was created using the software package [Fritzing](http://fritzing.org/download/).
Use Adafruit's Fritzing parts library to create circuit diagrams for your projects. Download the library or just grab individual parts. Get the library and parts from [GitHub - Adafruit Fritzing Parts](https://github.com/adafruit/Fritzing-Library/tree/master/parts).
## Wired Connections
The Circuit Playground Bluefruit is powered by a 500mAh battery.
## NeoPixel Ring
The back side of the ornament is illuminated by a 16 NeoPixel Ring.
- **V+** from **NeoPixel Ring** to **Vout** on **Circuit Playground **
- **G** from **NeoPixel Ring** to **GND** on **Circuit Playground**
- **IN** from **NeoPixel Ring** to **A1** on **Circuit Playground**

## CircuitPython on Circuit Playground Bluefruit
# Install or Update CircuitPython
Follow this quick step-by-step to install or update CircuitPython on your Circuit Playground Bluefruit.
[Download the latest version of CircuitPython for this board via circuitpython.org](https://circuitpython.org/board/circuitplayground_bluefruit/)
**Click the link above and download the latest UF2 file**
Download and save it to your Desktop (or wherever is handy)
Plug your Circuit Playground Bluefruit into your computer using a known-good data-capable USB cable.
**A lot of people end up using charge-only USB cables and it is very frustrating! So make sure you have a USB cable you know is good for data sync.**
Double-click the small **Reset** button in the middle of the CPB (indicated by the red arrow in the image). The ten NeoPixel LEDs will all turn red, and then will all turn green. If they turn all red and stay red, check the USB cable, try another USB port, etc. The little red LED next to the USB connector will pulse red - this is ok!
If double-clicking doesn't work the first time, try again. Sometimes it can take a few tries to get the rhythm right!
(If double-clicking doesn't do it, try a single-click!)
You will see a new disk drive appear called **CPLAYBTBOOT**.
Drag the **adafruit\_circuitpython\_etc.uf2** file to **CPLAYBTBOOT.**
The LEDs will turn red. Then, the **CPLAYBTBOOT** drive will disappear and a new disk drive called **CIRCUITPY** will appear.
That's it, you're done! :)

## Code
Once you've finished setting up your Circuit Playground Bluefruit with CircuitPython, you can access the code and necessary libraries by downloading the Project Bundle.
To do this, click on the ** Download Project Bundle** button in the window below. It will download as a zipped folder.
https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/Pumpkin_Goblin_CPB_Ornament/code.py
## Upload the Code and Libraries to the Circuit Playground Bluefruit
After downloading the Project Bundle, plug your Circuit Playground Bluefruit into the computer USB port. You should see a new flash drive appear in the computer's File Explorer or Finder (depending on your operating system) called **CIRCUITPY**. Unzip the folder and copy the following items to the Circuit Playground Bluefruit's **CIRCUITPY** drive.
- **lib** folder
- **code.py**
Your Circuit Playground Bluefruit **CIRCUITPY** drive should look like this after copying the **lib** folder and **code.py** file.

## Assemble
## Solder NeoPixel ring
Measure and cut wires to connect the Circuit Playground to the 16 Neopixel ring. Use third helping hands to hold the boards steady while soldering.
##
## CPB mount
Align the slit on the printed Circuit Playground mount to allow the wires to pass through. Align the JST port to the slit on the printed mount.
## Press fit NeoPixel ring
Center the ring to the mount and press one side of the ring until it press fits into the wall around the printed mount.
## Insert battery
Align the battery between the Circuit playground standoffs. Carefully bend the battery cable towards the slit on the printed mount.
## Press fit Circuit Playground
Use the snaps on each side of the mount to hold the Circuit Playground in place. Place one side of the board under one of the snaps. Gently press the opposite side of the board to attach it to the mount.
## Press fit mount into Ornament
Plug the battery into the JST port on the Circuit Playground. Allow the battery cable to press against the wall of the ornament. Gently press fit the printed mount into the Ornament.
## Diffusion
Use a sheet of parchment paper to help diffuse the ornament.
Align the tabs on the each half of the ornament and press fit both sides together.
## Attach Printed shells
Align the bottom printed shell to the tabs on the ornament. Press fit the tab into the printed shell.
The optional screw mounts on the sides of the shells are used to help align both halves together. Apply a small amount of force to snap fit both shells together.
Add a hook to adorne to a tree or use as a stand alone prop for a Green Goblin cosplay!
