# LO-LA59 Droid
## Overview
https://youtu.be/g1PIfCzxiTE
Build Lola, the companion droid to young Princess Leia.
This cute shoulder bot emotes by flapping her wings and blinking both LED eyes. Small and light enough to carry around on your next mission!
Embedded magnets allow Lola to attach to your shoulder or metal surfaces!
## Animatronic Wings
Two micro servos articulate each wing by pushing under the panel. This makes it simple to assemble and less likely to strip the servos.
## Mount with Magnets
The bottom of the body feature spots for press fitting magnets to attach to legs, shoulders or metal objects!
## ItsyBitsy RP2040
Powered by the ItsyBitsy RP2040. This dev board is packed with lots of great features and has the ability to use both Arduino and CircuitPython.

## Circuit Diagram
The wiring diagram below provides a visual reference for connecting the components. It is not true to scale, it is just meant to be used as reference. This diagrams was created using the [Fritzing software package](http://fritzing.org/download/).
Take a moment to review the components in the circuit diagram. This illustration is meant for referencing wired connections - the length of wire, position and size of components are not exact.
Wires are measured and cut to have enough slack to reach each component.
Silicone ribbon wire is used to make them easier to coil and manage each wire inside the tight enclosure space.
## Wired Connections
The two micro-servos share voltage, ground and signal connections.
NeoPixel to ItsyBisty
- DIN from NeoPixel to pin 5 on ItsyBitsy
- 5V from NeoPixel to VHI on ItsyBitsy
- GND from NeoPixel to GND on ItsyBitsy

## 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](https://circuitpython.org/board/adafruit_itsybitsy_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)
# LO-LA59 Droid
## Code
Once you've finished setting up your ItsyBitsy 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 as a zipped folder.
https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/Lola_Droid/code.py
## Upload the Code and Libraries to the ItsyBitsy
After downloading the Project Bundle, plug your board 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 PyPortal's **CIRCUITPY** drive.
- **lib** folder
- **code.py**
Your PyPortal **CIRCUITPY ** drive should look like this after copying the **lib** folder and the **code.py ** file.

## Assemble
## Solder Boards
Follow the circuit diagram to connect the two boards together.
Place the components over the mounts on the case to measure wire length.
## Connectors
Use male and female headers to easy connect the two servos and two NeoPixel boards. You may use kapton tape to seal the connections.
## Mount Magnet
Align the magnet pin to press fit through the cutouts on the case.
## Mount boards
The ItsyBitsy, Lipo backpack and slide switch press fit into the bottom body. Align the ItsyBitsy USB port to the opening of the case.
## Mount Servo to Center Body
Place the two servos with the mounting holes against the flat walls of the center body part.
## Servo Horns
The left horn attaches to the servo with the corner cut out on the case. Use the included screws to secure both horns to each servo.
## Thread wires
Push the two servo wires into the center hole on the case. Coil the wires to avoid cutting them short.
## Align Bottom and Center Body
Rotate the **Bottom Part** so the USB port opening points towards the back of Lola. Orient the **Center Body** part so the two holes (LED eyes) face the opposite side of the USB port.
Pass the two LED wires from the underside of the **Center Part** to the top.
Place the battery on same side as the slide switch. The battery plugs into the JST port on the lipo backpack board.
## Connects
Plug all the connectors together.
## Attach Center to Bottom Body
Align the **Bottom Body** part clips to the center body grooves.
Use a [Spudger tool](https://www.adafruit.com/product/3434) to disassemble if needed.
## Wing Assemble
A metal paper clip is used to create the pin for the wings. Use Precision Flat Pliers to carefully bend the wire to fit the curvature of the wing tabs.
Warning:
## Tail Assemble
Align the tail so the cut corner faces the eyes. This allows the tail to fully fold forward for transporting the droid.
## Connect NeoPixels
Solder male headers to the NeoPixel Jewel and NeoPixel Button.
Pass the LED wires into the **Top Body** cut outs.
## Attach Top Body
Align the clips on the top body part to the grooves on the **Center Body** part. Seat the first to clips into the groove then the press fit the last two clips into the grooves.
## Attach diffuser domes
Connect the Neopixel boards to the wires.
## Complete
Use skate lubricant to help the wings to flap smoothly.
