# Soundbox RP2040 ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/130/618/medium800/led_pixels_hero-pink.jpg?1718032116) Build a fun soundbox project using CircuitPython and Adafruit PropMaker Feather RP2040! This massive arcade button plays different sounds each time it's pressed. Embedded inside the arcade button is a NeoPixel strip that lights up when pressed. Each audio file features a color in the file name that corresponds with the NeoPixels, so you can choose a different color for each sound! ## What's Shaking? Shaking the device will trigger a different set of audio files with an accompanying NeoPixel rainbow! Thanks to the PropMaker Feather built-in accelerometer, it can easily detect when it's being shaken. ![led_pixels_shake-loop.gif](https://cdn-learn.adafruit.com/assets/assets/000/130/617/medium640thumb/led_pixels_shake-loop.jpg?1718030923) ## 3D Printed Enclosure The 3D printed enclosure features a speaker grill, chamfered edges and two hinged handles with access to the Feather USB-C port. The top and bottom covers snap fit, so it's easy to open for changing out the batteries. ![led_pixels_hero-handles.jpg](https://cdn-learn.adafruit.com/assets/assets/000/130/621/medium640/led_pixels_hero-handles.jpg?1718038179) ## Kid Friendly This project uses AA batteries for a safe kid friendly device.

It makes it easier than ever to get prototyping by requiring no upfront desktop software downloads. Simply copy and edit files on the **CIRCUITPY** drive to iterate. ## CircuitPython Quickstart Follow this step-by-step to quickly get CircuitPython running on your board. [Download the latest version of CircuitPython for this board via circuitpython.org](https://circuitpython.org/board/adafruit_feather_rp2040_prop_maker/) **Click the link above to download the latest CircuitPython UF2 file.** Save it wherever is convenient for you. ![install_circuitpython_on_rp2040_RP2040_UF2_downloaded.jpg](https://cdn-learn.adafruit.com/assets/assets/000/101/655/medium640/install_circuitpython_on_rp2040_RP2040_UF2_downloaded.jpg?1618943202) ![](https://cdn-learn.adafruit.com/assets/assets/000/121/865/medium800/adafruit_products_boot_reset.jpg?1686710555) To enter the bootloader, hold down the **BOOT/**** BOOTSEL button**(highlighted in red above), and while continuing to hold it (don't let go!), press and release the**reset button**(highlighted in red or blue above). **Continue to hold the BOOT/BOOTSEL button until the RPI-RP2 drive appears!** If the drive does not appear, release all the buttons, and then repeat the process above. You can also start with your board unplugged from USB, press and hold the BOOTSEL button (highlighted in red above), continue to hold it while plugging it into USB, and wait for the drive to appear before releasing the button. A lot of people end up using charge-only USB cables and it is very frustrating! **Make sure you have a USB cable you know is good for data sync.** You will see a new disk drive appear called **RPI-RP2**.   Drag the **adafruit\_circuitpython\_etc.uf2** file to **RPI-RP2.** ![install_circuitpython_on_rp2040_RP2040_bootloader_drive.jpg](https://cdn-learn.adafruit.com/assets/assets/000/101/656/medium640/install_circuitpython_on_rp2040_RP2040_bootloader_drive.jpg?1618943666) ![install_circuitpython_on_rp2040_RP2040_drag_UF2.jpg](https://cdn-learn.adafruit.com/assets/assets/000/101/657/medium640/install_circuitpython_on_rp2040_RP2040_drag_UF2.jpg?1618943674) The **RPI-RP2** drive will disappear and a new disk drive called **CIRCUITPY** will appear. That's it, you're done! :) ![install_circuitpython_on_rp2040_RP2040_CIRCUITPY.jpg](https://cdn-learn.adafruit.com/assets/assets/000/101/658/medium640/install_circuitpython_on_rp2040_RP2040_CIRCUITPY.jpg?1618943864) ## Safe Mode You want to edit your **code.py** or modify the files on your **CIRCUITPY** drive, but find that you can't. Perhaps your board has gotten into a state where **CIRCUITPY** is read-only. You may have turned off the **CIRCUITPY** drive altogether. Whatever the reason, safe mode can help. Safe mode in CircuitPython does not run any user code on startup, and disables auto-reload. This means a few things. First, safe mode _bypasses any code in_ **boot.py** (where you can set **CIRCUITPY** read-only or turn it off completely). Second, _it does not run the code in_ **code.py**. And finally, _it does not automatically soft-reload when data is written to the_ **CIRCUITPY** _drive_. Therefore, whatever you may have done to put your board in a non-interactive state, safe mode gives you the opportunity to correct it without losing all of the data on the **CIRCUITPY** drive. ### Entering Safe Mode To enter safe mode when using CircuitPython, plug in your board or hit reset (highlighted in red above). Immediately after the board starts up or resets, it waits 1000ms. On some boards, the onboard status LED (highlighted in green above) will blink yellow during that time. If you press reset during that 1000ms, the board will start up in safe mode. It can be difficult to react to the yellow LED, so you may want to think of it simply as a slow double click of the reset button. (Remember, a fast double click of reset enters the bootloader.) ### In Safe Mode If you successfully enter safe mode on CircuitPython, the LED will intermittently blink yellow three times. If you connect to the serial console, you'll find the following message. ```terminal Auto-reload is off. Running in safe mode! Not running saved code. CircuitPython is in safe mode because you pressed the reset button during boot. Press again to exit safe mode. Press any key to enter the REPL. Use CTRL-D to reload. ``` You can now edit the contents of the **CIRCUITPY** drive. Remember, _your code will not run until you press the reset button, or unplug and plug in your board, to get out of safe mode._ ## Flash Resetting UF2 If your board ever gets into a really _weird_ state and CIRCUITPY doesn't show up as a disk drive after installing CircuitPython, try loading this 'nuke' UF2 to RPI-RP2. which will do a 'deep clean' on your Flash Memory. **You will lose all the files on the board** , but at least you'll be able to revive it! After loading this UF2, follow the steps above to re-install CircuitPython. [Download flash erasing "nuke" UF2](https://cdn-learn.adafruit.com/assets/assets/000/101/659/original/flash_nuke.uf2?1618945856) # Soundbox RP2040 ## Code the Soundbox Once you've finished setting up your RP2040 Prop-Maker Feather 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 to your computer as a zipped folder. https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/CircuitPython_Sound_Box_2/code.py ## Upload the Code, Sound Effects, and Libraries to the RP2040 Prop-Maker Feather After downloading the Project Bundle, plug your RP2040 Prop-Maker Feather into the computer's USB port with a known good USB data+power cable. 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 Feather's **CIRCUITPY** drive: - **lib** folder - **wavs** folder - **code.py** Your RP2040 Prop-Maker Feather **CIRCUITPY** drive should look like this after copying the **lib** folder, **wavs** folder and the **code.py** file. ![CIRCUITPY](https://adafruit.github.io/Adafruit_Learning_System_Guides/CircuitPython_Sound_Box_2.png ) ## How the CircuitPython Code Works The code begins by turning on the `EXTERNAL_POWER` pin on the Feather. This pin controls the power to the terminal block pins. The NeoPixels and button use the `EXTERNAL_NEOPIXELS` and `EXTERNAL_BUTTON` pins. ```python # enable external power pin # provides power to the external components external_power = DigitalInOut(board.EXTERNAL_POWER) external_power.direction = Direction.OUTPUT external_power.value = True # external neopixels num_pixels = 24 pixels = neopixel.NeoPixel(board.EXTERNAL_NEOPIXELS, num_pixels, brightness=0.4, auto_write=True) # external button switch = keypad.Keys((board.EXTERNAL_BUTTON,), value_when_pressed=False, pull=True) ``` ## Dictionary of Colors A dictionary is used to list color names and color HEX codes. ```python colors = [ {'label': "BLUE", 'color': 0x0000FF}, {'label': "RED", 'color': 0xFF0000}, {'label': "GREEN", 'color': 0x00FF00}, {'label': "YELLOW", 'color': 0xFFFF00}, {'label': "AQUA", 'color': 0x00FFFF}, {'label': "PURPLE", 'color': 0xFF00FF}, {'label': "PINK", 'color': 0xFF0055}, {'label': "ORANGE", 'color': 0xFF5500}, {'label': "WHITE", 'color': 0x555555}, ] ``` ## Sorting Audio The audio files from the wavs folder are sorted into two different arrays: `shake_wavs` and `color_wavs`. They are sorted based on the name of the file. If "`SHAKE`" is in the file name, then it is added to `shake_wavs`. If the file name has one of the color labels from the `colors` dictionary, then it is added to `color_wavs`. ```python shake_wavs = [] color_wavs = [] for filename in os.listdir('/wavs'): if filename.lower().endswith('.wav') and not filename.startswith('.'): if "SHAKE" in filename: shake_wavs.append("/wavs/" + filename) else: for color in colors: if color['label'] in filename: color_wavs.append("/wavs/" + filename) break ``` ## The Loop In the loop, the `keypad` object is scanned for an `event`. If the switch is pressed, then one of the sound files that was sorted into the `color_wavs` array is opened and played. The NeoPixel ring lights up with the same color that is contained in the name of the audio file. ```python while True: event = switch.events.get() if event: if event.pressed: wave, wave_name = open_audio(random.randint(0, num_colors - 1), color_wavs) audio.play(wave) for color in colors: if color['label'] in wave_name: pixels.fill(color['color']) else: pass time.sleep(.7) pixels.fill((0, 0, 0)) print('pressed') ``` If the LIS3DH detects a `shake`, then one of the audio files from the `shake_wavs` is opened and played. The NeoPixels light up with a rainbow effect. ```python if lis3dh.shake(shake_threshold=12): wave, wave_name = open_audio(random.randint(0, num_shakes - 1), shake_wavs) audio.play(wave) for i in range(num_pixels): pixels[i] = colorwheel(hue) hue = (hue + 30) % 256 print(hue) time.sleep(.7) pixels.fill((0, 0, 0)) print('shake') ``` # Soundbox RP2040 ## Wiring ## Slide Switch Wiring Cut two wires to 2.5 inches (6cm) in length. Snip off one of the leads on the slide switch, either the far left or right but not the middle. Then, trim the two remaining leads short, about half their length. Solder the two wires to each of the leads on the slide switch. ![led_pixels_switch-wire.jpg](https://cdn-learn.adafruit.com/assets/assets/000/130/541/medium640/led_pixels_switch-wire.jpg?1718021930) ![led_pixels_switch-solder.jpg](https://cdn-learn.adafruit.com/assets/assets/000/130/542/medium640/led_pixels_switch-solder.jpg?1718021940) ## Wire Slide Switch to Feather Solder the two wires from the slide to the EN and GND pins on the top of the Feather. Take a moment to ensure the wires from the slide switch have been properly soldered. ![led_pixels_switch-feather-solder.jpg](https://cdn-learn.adafruit.com/assets/assets/000/130/543/medium640/led_pixels_switch-feather-solder.jpg?1718021955) ![led_pixels_feather-switch-wired.jpg](https://cdn-learn.adafruit.com/assets/assets/000/130/544/medium640/led_pixels_feather-switch-wired.jpg?1718021971) ## Disable Battery LiPo Charging Use a sharp hobby knife to cut the LiPo Charging trace on the back of the PropMaker Feather RP2040. This must be cut to prevent accidental calamity with alkaline batteries when USB is plugged in. ![led_pixels_feather-cut-trace.jpg](https://cdn-learn.adafruit.com/assets/assets/000/130/620/medium640/led_pixels_feather-cut-trace.jpg?1718038002) Warning: Be careful using a hobby knife. Use gloves and caution. An older person should do this for a young maker. ## NeoPixel Strip Start by removing the NeoPixel strip from the reel. Remove the stock cable from the beginning of the strip using wire cutters.  Measure and cut a piece from the strip so it has 24 NeoPixel LEDs in the cut piece. Remove the silicone sheathing from the cut piece. ![led_pixels_strip-length.jpg](https://cdn-learn.adafruit.com/assets/assets/000/130/545/medium640/led_pixels_strip-length.jpg?1718021990) ## Solder Wires to the NeoPixels Measure and cut a piece from the 4-wire silicone ribbon cable so it's 8 inches (20cm) in length, then strip off one of the wires, we only need three. Locate the end of the NeoPixel strip with the  **DI**  (Data In)  label. Solder the three wires from the cable to the pads on the front of the NeoPixel strip. ![led_pixels_strip-wiring.jpg](https://cdn-learn.adafruit.com/assets/assets/000/130/546/medium640/led_pixels_strip-wiring.jpg?1718022021) ## Wired NeoPixel Strip Double check the wires are properly soldered to  **5V** ,  **DI**  and  **GND**  pads on the NeoPixel LED strip. ![led_pixels_strip-wired.jpg](https://cdn-learn.adafruit.com/assets/assets/000/130/547/medium640/led_pixels_strip-wired.jpg?1718022042) ## Quick Connect Cable Grab one quick-connect cable from the pack. Cut the end with the JST connector so the two wires are about 6 inches in length (15cm). Using wire strippers, remove a bit of insulation from each wire. Tin the exposed wire using solder to prevent the strands of wire from fraying. ![led_pixels_quick-cables.jpg](https://cdn-learn.adafruit.com/assets/assets/000/130/602/medium640/led_pixels_quick-cables.jpg?1718023939) # Soundbox RP2040 ## Arcade Button Assembly ## Remove Switch & LED Remove the micro switch from the arcade button by twisting it counter clock-wise and pulling it out. Remove the LED from the micro switch housing by pulling it straight out. Set the LED aside, it won't be used in this project so you can save it for another project.  ![led_pixels_arcade-button-switch.jpg](https://cdn-learn.adafruit.com/assets/assets/000/130/567/medium640/led_pixels_arcade-button-switch.jpg?1718022538) ![led_pixels_arcade-button-led.jpg](https://cdn-learn.adafruit.com/assets/assets/000/130/568/medium640/led_pixels_arcade-button-led.jpg?1718022555) ## Remove Nut & Plate Unscrew the plastic nut from the arcade button threading. The arcade button plate should freely come out of the button housing. Set the arcade button plate aside, it won't be used in the final build. ![led_pixels_arcade-button-nut.jpg](https://cdn-learn.adafruit.com/assets/assets/000/130/569/medium640/led_pixels_arcade-button-nut.jpg?1718022582) ![led_pixels_arcade-button-plate.jpg](https://cdn-learn.adafruit.com/assets/assets/000/130/570/medium640/led_pixels_arcade-button-plate.jpg?1718022593) ## Remove Button Actuator Use a wide flat tool (LEGO brick separator shown in photo) to push the internal spring. Use your fingers to pinch the two white prongs. Push the white prongs through the button threading and pull out the white housing from the black button housing. ![led_pixels_arcade-button-spring-removal.jpg](https://cdn-learn.adafruit.com/assets/assets/000/130/571/medium640/led_pixels_arcade-button-spring-removal.jpg?1718022608) ![led_pixels_arcade-button-actuator.jpg](https://cdn-learn.adafruit.com/assets/assets/000/130/572/medium640/led_pixels_arcade-button-actuator.jpg?1718022625) ## Remove Dome & Cover Use the spudger tool to pry the clear plastic dome from the white button housing.  Fit the edge of the tool in between the clear plastic dome and white button housing then lift to pry them apart. A white cover diffuser should freely come out of the clear plastic dome. ![led_pixels_arcade-button-dome.jpg](https://cdn-learn.adafruit.com/assets/assets/000/130/573/medium640/led_pixels_arcade-button-dome.jpg?1718022642) ## Disassembled Arcade Button With the arcade button fully disassembled, take a moment to inspect all the parts are accounted for.  ![led_pixels_arcade-button-parts.jpg](https://cdn-learn.adafruit.com/assets/assets/000/130/574/medium640/led_pixels_arcade-button-parts.jpg?1718022667) ## LED Strip Holder Get the white button housing, wired NeoPixel strip and 3D printed strip holder ready. ![led_pixels_arcade-button-strip-holder.jpg](https://cdn-learn.adafruit.com/assets/assets/000/130/575/medium640/led_pixels_arcade-button-strip-holder.jpg?1718022701) ## Install LED Strip to Holder Insert the NeoPixel strip into the 3D printed strip holder with the starting end fitted through the slit in the holder.
