# Motorized POV LED Display
## Overview
## Holographic-like Images
Build an LED display that creates an optical illusion. POV (Persistence of Vision) is an effect that occurs when the human eye continues to see an image after it has disappeared from view.
This project uses a motor to spin two strips of DotStar LEDs to achieve a POV effect.
The CircuitPython code converts a bitmap image to blink the DotStar LEDs when in motion, creating the POV effect.
## Modular Build
3D printed panels, mounts, and gears create the mechanical structure to house the electronics. A slip ring allows the wired connections to rotate without tangling up.
A Feather RP2040 and DC Motor FeatherWing sit on a FeatherWing Doubler, creating a modular system.

# Motorized POV LED Display
## Install CircuitPython
[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** 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/)
**Click the link above to download the latest CircuitPython UF2 file.**
Save it wherever is convenient for you.
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.**
The **RPI-RP2** drive will disappear and a new disk drive called **CIRCUITPY** will appear.
That's it, you're done! :)
## 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)
# Motorized POV LED Display
## Code the POV LED Display
Once you've finished setting up your Feather RP2040 Propmaker 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/Motorized_POV_Display/code.py
## Upload the code, images and Libraries to the Feather RP2040
After downloading the Project Bundle, plug your Feather RP2040 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 RP2040's **CIRCUITPY** drive.
- **lib** folder
- **code.py**
- **blinka.bmp**
- **sans.bmp**
- **dreidel.bmp**
- **nyan-xmas.bmp**
- **pipesky.bmp**
- **xmas.bmp**
- **xmastree.bmp**
Your Feather RP2040 **CIRCUITPY** drive should look like this after copying the **lib** folder, images and the **code.py** file.
## Adjusting Image
At the top of the code, there are some user configurable settings that you can edit.
- `FILENAME` is the title of the image the display will draw. Change this variable to the desired image name to display
- `BRIGHTNESS` affects the overall brightness of the LEDs
- `PIXEL_DELAY` affects how the image is scaled when in motion. If the image appears stretched, lower the number. If it appears squished, increase the number
```python
FILENAME = "nyan-xmas.bmp"
IMAGE_DELAY = 0.001
REPEAT = True
BRIGHTNESS = 0.3
PIXEL_DELAY = 0.003
```

## Prep FeatherWing Wiring
The wires on the bottom of the slip ring will connect to the pins on the bottom of the FeatherWing Doubler PCB.
## Connect Slip Ring to Doubler
Locate the pins on the FeatherWing Doubler by referencing the pin labels on Feather RP2040. Make the following connections on the bottom of the PCB.
- Solder the **red** wire from the slip ring to a **3V** pin on the Doubler
- Solder the **black** wire from the slip ring to a **GND** pin on the Doubler
- Solder the **yellow** wire from the slip ring to the **SCK** pin on the Doubler
- Solder the **green** wire from the slip ring to the **MO** pin on the Doubler
## Install Feather RP2040 and Motor FeatherWing Headers
Solder the headers onto the Feather RP2040 and Motor FeatherWing.
## LED Power Test
Install the Feather RP2040 and Motor FeatherWing onto the FeatherWing Doubler.
Connect the two DotStar LED strips to the two 4-pin cables on the slip ring.
Provide 5V 1A power to the Feather RP2040 to test the circuit. The LEDs should start blinking.
## DC Jack Wires
Prep two wires, preferably red and white, to connect the DC Power adapter to the Motor FeatherWing. Wires should measure to approximately 3 inches (76mm) in length.
Connect the red wire to the positive screw terminal block and the black to the negative screw terminal block.
