The alligator clips are color coded so that you can tell which connection goes where. ## Wiring Diagram ![](https://cdn-learn.adafruit.com/assets/assets/000/115/663/medium800/projects_neoPixelClue_bb.png?1664904750) - **NeoPixel Data In** to **CLUE pad 0 (white wire)** - **NeoPixel Power** to **CLUE 3V pad (red wire)** - **NeoPixel Ground** to **CLUE GND pad (black wire)** ## Assembly First, make sure that your CLUE is disconnected from power. Then, clip the **NeoPixel strip's white alligator clip** to the **CLUE's pad 0**. This is the data input for the NeoPixel strip. ![projects_edited_P1380927.jpg](https://cdn-learn.adafruit.com/assets/assets/000/115/652/medium640/projects_edited_P1380927.jpg?1664896052) Next, clip the **NeoPixel strip's red alligator clip** to the **CLUE's 3V pad**. This is the power input for the NeoPixel strip. ![projects_edited_P1380929.jpg](https://cdn-learn.adafruit.com/assets/assets/000/115/653/medium640/projects_edited_P1380929.jpg?1664896065) Finally, clip the **NeoPixel strip's black alligator clip** to the **CLUE's GND pad**. This is the ground connection for the NeoPixel strip. ![projects_edited_P1380933.jpg](https://cdn-learn.adafruit.com/assets/assets/000/115/654/medium640/projects_edited_P1380933.jpg?1664896067) Now your NeoPixel strip is connected to your CLUE! # PyLeap BLE Controlled NeoPixels with CLUE ## CircuitPython on CLUE [CircuitPython](https://github.com/adafruit/circuitpython) is a derivative of [MicroPython](https://micropython.org) designed to simplify experimentation and education on low-cost microcontrollers. It makes it easier than ever to get prototyping by requiring no upfront desktop software downloads. Simply copy and edit files on the **CIRCUITPY**  flash drive to iterate. The following instructions will show you how to install CircuitPython. If you've already installed CircuitPython but are looking to update it or reinstall it, the same steps work for that as well! ## Set up CircuitPython Quick Start! Follow this quick step-by-step for super-fast Python power :) [Download the latest version of CircuitPython for CLUE from circuitpython.org](https://circuitpython.org/board/clue_nrf52840_express/) **Click the link above to download the latest version of CircuitPython for the CLUE.** Download and save it to your desktop (or wherever is handy). ![adafruit_products_CLUE_UF2_Downloaded.png](https://cdn-learn.adafruit.com/assets/assets/000/088/037/medium640/adafruit_products_CLUE_UF2_Downloaded.png?1580840077) Plug your CLUE into your computer using a known-good 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 **Reset** button on the top (magenta arrow) on your board, and you will see the NeoPixel RGB LED (green arrow) turn green. If it turns red, check the USB cable, try another USB port, etc. **Note:** The little red LED next to the USB connector will pulse red. That's ok! If double-clicking doesn't work the first time, try again. Sometimes it can take a few tries to get the rhythm right! ![adafruit_products_Clue_Reset_NeoPixel_bootloader.png](https://cdn-learn.adafruit.com/assets/assets/000/087/919/medium640/adafruit_products_Clue_Reset_NeoPixel_bootloader.png?1580496467) You will see a new disk drive appear called **CLUEBOOT**. Drag the **adafruit-circuitpython-clue-etc.uf2** file to **CLUE**** BOOT.** ![adafruit_products_CLUE_CLUEBOOT.png](https://cdn-learn.adafruit.com/assets/assets/000/088/042/medium640/adafruit_products_CLUE_CLUEBOOT.png?1580841287) ![adafruit_products_CLUE_drag_UF2.png](https://cdn-learn.adafruit.com/assets/assets/000/088/043/medium640/adafruit_products_CLUE_drag_UF2.png?1580841295) The LED will flash. Then, the **CLUEBOOT** drive will disappear and a new disk drive called **CIRCUITPY** will appear. If this is the first time you're installing CircuitPython or you're doing a completely fresh install after erasing the filesystem, you will have two files - **boot\_out.txt** , and **code.py** , and one folder - **lib** on your **CIRCUITPY** drive. If CircuitPython was already installed, the files present before reloading CircuitPython should still be present on your **CIRCUITPY** drive. Loading CircuitPython will not create new files if there was already a CircuitPython filesystem present. That's it, you're done! :) ![adafruit_products_CLUE_CIRCUITPY.png](https://cdn-learn.adafruit.com/assets/assets/000/088/044/medium640/adafruit_products_CLUE_CIRCUITPY.png?1580841453) # PyLeap BLE Controlled NeoPixels with CLUE ## Pairing Now that you're done uploading the correct firmware, **disconnect** your device from your computer and power it via [LiPoly](https://www.adafruit.com/category/574) or [AAA battery pack](https://www.adafruit.com/product/727). ## Pairing device to PyLeap Once powered, press the small  **Reset** button in the center of the board (Circuit Playground Bluefruit) or on the top right of the board (CLUE). When the blue light flashes, press the Reset button again. ![Circuit Playground Bluefruit with reset button in center of board](https://cdn-learn.adafruit.com/assets/assets/000/107/090/medium800thumb/circuit_playground_ezgif22.jpg?1664908526 Circuit Playground Bluefruit with a small Reset button in the center of the board) ![Adafruit](https://cdn-learn.adafruit.com/assets/assets/000/087/865/original/adafruit_products_Clue_pinouts_Reset.png?1580413920 Adafruit CLUE Reset Button (Highlighted on the upper right)) When done correctly, the LEDs will flash yellow followed by solid blue. Once this occurs, the board will **continuously** be in discovery mode. ## Scan & Connect When your Circuit Playground Bluefruit or Adafruit CLUE is in discovery mode, hold it very closely to your iPhone or iPadOS to pair.  ![](https://cdn-learn.adafruit.com/assets/assets/000/112/226/medium800thumb/circuitpython_ezgif.com-gif-maker-3.jpg?1654190148) Below the spinning Blinka, you'll notice a status indicator that will let you know your current **pairing status.** Once you've found your device and received the **Bluetooth Pairing Request** message, press Pair to pair your board to your iPhone or iPadOS. ![](https://cdn-learn.adafruit.com/assets/assets/000/112/232/medium800/circuitpython_IMG_6159.png?1654209813) ## If your Circuit Playground Bluefruit doesn't appear: 1. Check to see if your Circuit Playground Bluefruit is powered on. Verify that the green **On** light is lit. 2. Make sure your Circuit Playground Bluefruit is running the correct **firmware**. See the [CircuitPython page](https://learn.adafruit.com/pyleap-app/circuitpython) in this guide. 3. Try resetting the Circuit Playground Bluefruit by pressing the small **Reset** button near the center of the board. # PyLeap BLE Controlled NeoPixels with CLUE ## BLE Controlled NeoPixels Code ![](https://cdn-learn.adafruit.com/assets/assets/000/115/664/medium800/projects_edited_P1380940.jpg?1664904980) https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/PyLeap/PyLeap_CLUE_BLE_NeoPixels/code.py # PyLeap BLE Controlled NeoPixels with CLUE ## Bluefruit Connect App ![](https://cdn-learn.adafruit.com/assets/assets/000/115/666/medium800/projects_connectToBLE0.jpg?1664905189) After loading the project onto your CLUE with PyLeap, close out of the PyLeap app. This disconnects the CLUE from PyLeap. Now, your CLUE display will show "CONNECT TO BLE", signaling that it's ready to connect to the [Bluefruit Connect App](https://learn.adafruit.com/bluefruit-le-connect). Follow along with the next two pages to download and install the app and then connect to the CLUE with it.
