# NeoPixel Menorah ## Overview https://youtu.be/3yg3KPm4CSA ![](https://cdn-learn.adafruit.com/assets/assets/000/106/822/medium800/led_pixels_hero-2.jpg?1637685648) In this guide you'll learn how to build a 3D printed Menorah that lights up with NeoPixel LEDs and CircuitPython. This minimalistic design features parts that snap fit together and print without any supports. The assembly is modular and easy to put together. ## Light Up The Days A push button allows you to light up a NeoPixel LED on each night of Hanukkah. The Shamash (center NeoPixel) stays lit each night. On the first night of Hanukkah, the NeoPixel LED on the far right is lit. Just press the button each night to light up the next one. ![led_pixels_guide-loop-2.gif](https://cdn-learn.adafruit.com/assets/assets/000/106/789/medium640thumb/led_pixels_guide-loop-2.jpg?1637679795) ## 3D Printed Bulbs The bulbs are printed in translucent PLA and the NeoPixels are fitted inside these little holders. The bulbs are hollow to better diffuse the LEDs so they’ll illuminate nicely. ![leds_bulb-neopixels.jpg](https://cdn-learn.adafruit.com/assets/assets/000/106/769/medium640/leds_bulb-neopixels.jpg?1637592227) ## USB-C Powered The bottom has a cut out so you have access to the USB-C port. It can be powered by a 5V USB supply from either a computer or a wall outlet. ![leds_hero-usb-port.jpg](https://cdn-learn.adafruit.com/assets/assets/000/106/772/medium640/leds_hero-usb-port.jpg?1637592405) ## QT Py RP2040 This project is powered by the Adafruit QT Py RP2040 running CircuitPython. The QT Py is secured to the bottom cover and just snaps into the build-in holder. ![leds_hero-qtpy.jpg](https://cdn-learn.adafruit.com/assets/assets/000/106/771/medium640/leds_hero-qtpy.jpg?1637592394) ![](https://cdn-learn.adafruit.com/assets/assets/000/106/823/medium800/led_pixels_hero-1.jpg?1637685660) ## Parts ### Adafruit QT Py RP2040 [Adafruit QT Py RP2040](https://www.adafruit.com/product/4900) What a cutie pie!

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_qtpy_rp2040/) **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/000/101/680/medium800/adafruit_products_QTRP_buttons.jpg?1618956837) 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.
