If you've never used the Circuit Playground Express with MakeCode before, [this guide is a good place to start](https://makecode.adafruit.com/courses/maker/general/coding). ![](https://cdn-learn.adafruit.com/assets/assets/000/080/864/medium800/makecode.jpg?1568403947) ## The Code The code is shown below. For browser viewing, you may need to enable content. For example, in Chrome, click "Show Embedded Content" as the material is fed not from Adafruit but from Microsoft's MakeCode site. To download the code, click the download link at the bottom of the window. To edit the code in MakeCode, click the box with arrow icon in the upper right corner of the window. https://makecode.adafruit.com/97994-71850-30457-86860 ## How to Upload Code To upload code to Circuit Playground Express, follow these instructions: 1) Connect your Circuit Playground Express to your computer using a known, good data+power micro USB cable and press the small reset button in the center of the board. All the LEDs will flash  **red ** briefly **, then turn green. ** Your computer should now show a removable drive called  **CPLAYBOOT. ** 2) Click the  **Download**  button in the code window below to download the ** .UF2 file**  to your computer. 3) Now ** drag and drop the .UF2 file onto the CPLAYBOOT**   **drive**  in your computer's file explorer or finder. Once the file is dragged onto  **CPLAYBOOT,**  the drive will automatically eject itself (your computer may give you a "failed to eject drive correctly" error, you can ignore this). The code is now on your Circuit Playground Express and ready to run! Note: If you get a drive named  **CIRCUITPY** , no worries! Press the reset button  **twice**  to get a flash drive named  **CPLAYBOOT**. The project will not run if copied onto the  **CIRCUITPY**  drive as it is for CircuitPython. ![](https://cdn-learn.adafruit.com/assets/assets/000/081/054/medium800/led_strips_Screen_Shot_2019-09-17_at_6.56.50_PM.png?1568761061) ## What Does This Code Do? The code for this project uses some built-in capacitive sensing abilities to detect when the sword is being held and when it's put down. In the `on start` statement we can see that `set strip to` block defines the length of the NeoPixel strip and which pin will control it (in this case **A1** ). It also simultaneously sets the brightness of the NeoPixel strip to 0 while calibrating the sensitivity of the capacitive touch pad **A7**. ![](https://cdn-learn.adafruit.com/assets/assets/000/081/067/medium800/led_strips_on_start.png?1568832192) In the first pink statement, the `on touch A7 down` command tells Circuit Playground Express to bring the brightness of the strip up to 200 and play the rainbow animation when it detects a change in capacitance. ![](https://cdn-learn.adafruit.com/assets/assets/000/081/069/medium800/led_strips_on_touch_A7_down.png?1568832207) Below, the `on touch A7 up` command tells the strip to fade its brightness slowly when the sword is no longer being touched, resulting in a return of the measured capacitance to baseline. ![](https://cdn-learn.adafruit.com/assets/assets/000/081/070/medium800/led_strips_on_touch_A7_up.png?1568832217) Lastly, some functionality is given to **button A** , allowing the user to recalibrate the touch sensitivity without needing to restart the board. ![](https://cdn-learn.adafruit.com/assets/assets/000/081/068/medium800/led_strips_on_button_A_click.png?1568832199) Info: ## Troubleshooting **Problem: ** My Circuit Playground Express doesn't show up as  **CPLAYBOOT** **Solutions:** 1. Be sure you have a Circuit Playground Express.  The Circuit Playground Classic will not work with MakeCode. 2. If you get a drive named  **CIRCUITPY**  instead, press the reset button twice in succession to get to  **CPLAYBOOT**. 3. Some USB cables are "charge-only" and won't pass data. Try using a different USB cable and try using a different USB port on your computer.   4. With the Circuit Playground Express plugged into your computer with a micro USB cable,  **click the small reset button**  in the center of the board. The lights should all turn green. If they don't, try  **double-clicking**  the reset button. If things still aren't working, head over to the Intro to [Circuit Playground Express](https://learn.adafruit.com/adafruit-circuit-playground-express) guide for more suggestions. For more information on using capacitive touch take a look at [this guide](https://learn.adafruit.com/circuitpython-made-easy-on-circuit-playground-express/capacitive-touch). # Magical Cardboard Craft Obsidian Sword ## Design Your Sword ## Sketch Outline   On a large piece of cardboard, sketch out the rough dimensions of your sword. Use the NeoPixel strip as a guide for how long to make the sword. Start with pencil, then define the outline with a dark marker. ![makecode_IMG_7217.jpg](https://cdn-learn.adafruit.com/assets/assets/000/080/838/medium640/makecode_IMG_7217.jpg?1568391475) ![makecode_IMG_7219.jpg](https://cdn-learn.adafruit.com/assets/assets/000/080/839/medium640/makecode_IMG_7219.jpg?1568391604) ![makecode_IMG_7220.jpg](https://cdn-learn.adafruit.com/assets/assets/000/080/840/medium640/makecode_IMG_7220.jpg?1568393441) ## Cut & Copy   Cut out the outline. Trace the outline on cardboard to create a duplicate. Because you're creating a copy of the original outline, you don't have to worry about being perfectly symmetrical. Make it as complicated as you like!  ![makecode_IMG_7221.jpg](https://cdn-learn.adafruit.com/assets/assets/000/080/841/medium640/makecode_IMG_7221.jpg?1568393517) ![makecode_IMG_7222.jpg](https://cdn-learn.adafruit.com/assets/assets/000/080/842/medium640/makecode_IMG_7222.jpg?1568393582) ![makecode_IMG_7223.jpg](https://cdn-learn.adafruit.com/assets/assets/000/080/843/medium640/makecode_IMG_7223.jpg?1568393609) ## NeoPixel Supports   Cut a variety of thin rectangles of cardboard about the same width as the NeoPixel strip. Glue these aroundthe sword, leaving about 1/4" from the outside edge.   These will act as the backing material to support the NeoPixel strip. ![makecode_IMG_7225.jpg](https://cdn-learn.adafruit.com/assets/assets/000/080/844/medium640/makecode_IMG_7225.jpg?1568393742) ![makecode_IMG_7287.jpg](https://cdn-learn.adafruit.com/assets/assets/000/080/845/medium640/makecode_IMG_7287.jpg?1568393782) ## Hot Glue Galore   Glue NeoPixel strip around outside edge. Use hot glue to pin the strip in place by applying it to the outside edge of the cardboard. ![makecode_IMG_7304.jpg](https://cdn-learn.adafruit.com/assets/assets/000/080/846/medium640/makecode_IMG_7304.jpg?1568393979) ![makecode_IMG_7306.jpg](https://cdn-learn.adafruit.com/assets/assets/000/080/847/medium640/makecode_IMG_7306.jpg?1568394045) ## Add CPX   Affix your Circuit Playground Express on the sword using double sided tape or hot glue.   Place it in a location where the alligator clips from the NeoPixel strips can still reach. ![makecode_IMG_7337.jpg](https://cdn-learn.adafruit.com/assets/assets/000/080/848/medium640/makecode_IMG_7337.jpg?1568394146) ![makecode_IMG_7339.jpg](https://cdn-learn.adafruit.com/assets/assets/000/080/849/medium640/makecode_IMG_7339.jpg?1568394186) ![makecode_IMG_7338.jpg](https://cdn-learn.adafruit.com/assets/assets/000/080/850/medium640/makecode_IMG_7338.jpg?1568394320) ## Handle   Use a cardboard tube to make a handle.  If you don't have one that happens to be the right size, one can be made from an existing cardboard tube that is cut lengthwise and rolled down to the correct diameter for your purposes. ![makecode_IMG_7335.jpg](https://cdn-learn.adafruit.com/assets/assets/000/080/851/medium640/makecode_IMG_7335.jpg?1568394418) ![makecode_IMG_7342.jpg](https://cdn-learn.adafruit.com/assets/assets/000/080/852/medium640/makecode_IMG_7342.jpg?1568394486) ## Touch Sensitivity   Make your handle touch sensitive by wrapping conductive nylon tape around the handle. Start by securely connecting the end of the tape to pad A7 on CPX. From there, wrap the tape around the handle, creating any pattern you desire. ![makecode_IMG_7420.jpg](https://cdn-learn.adafruit.com/assets/assets/000/080/946/medium640/makecode_IMG_7420.jpg?1568671715) ![makecode_IMG_7421.jpg](https://cdn-learn.adafruit.com/assets/assets/000/080/947/medium640/makecode_IMG_7421.jpg?1568671761) ![makecode_IMG_7443.jpg](https://cdn-learn.adafruit.com/assets/assets/000/080/948/medium640/makecode_IMG_7443.jpg?1568671837) ![](https://cdn-learn.adafruit.com/assets/assets/000/081/031/medium800/led_strips_IMG_7445.jpg?1568753267) ## Time to shine! Power on your CPX and give it a few seconds to calibrate its sensitivity, then you should be able to control the lights with your touch! ![](https://cdn-learn.adafruit.com/assets/assets/000/081/014/medium800/led_strips_IMG_7485.jpg?1568749086) # Magical Cardboard Craft Obsidian Sword ## Illuminate! ## Power On If you're powering the sword with a AAAx3 battery pack, flip the switch from OFF to ON. If you're using a LiPo battery, simply plug it in the the JST connector. ![makecode_IMG_7480.jpg](https://cdn-learn.adafruit.com/assets/assets/000/081/005/medium640/makecode_IMG_7480.jpg?1568748235) ## Calibrating the Sword When you turn on the sword it will take a couple seconds to calibrate itself. Don't touch it while it's calibrating! If you find the the NeoPixel strip isn't responding as you'd expect, you can press **button A**  on the Circuit Playground Express to re-run the calibration. Just be sure to put it down and don't touch it for a couple seconds while it's calibrating! ## Pick Up When you pick up the sword it should immediately come ablaze in response to your touch. ![](https://cdn-learn.adafruit.com/assets/assets/000/081/047/medium800thumb/led_strips_demo3.2019-09-17_18_07_26.jpg?1568759393) ## Put Down When you put down the sword it should slowly fade out. ![](https://cdn-learn.adafruit.com/assets/assets/000/081/046/medium800thumb/led_strips_put_down.2019-09-17_16_09_36.jpg?1568758286) ## More MakeCode!
