#  Faz-Wrench - Five Nights at Freddy's

## Overview

https://youtu.be/zr6lKUDzCZM

You can build a prop replica of the Faz Wrench from **Five Nights of Freddy’s Security Breach – Ruin**.

We designed and 3D printed this prop to use the RP2040 PropMaker Feather and CircuitPython.

It's got a working LCD with buttons, LEDs, rotary encoder and a speaker for sound effects.

 

![lcds___displays_hero-hold.jpg](https://cdn-learn.adafruit.com/assets/assets/000/125/176/medium640/lcds___displays_hero-hold.jpg?1697426307)

The RP2040 PropMaker Feather is packed with features for making advanced props in CircuitPython or Arduino.

 

The Adafruit LCD backpack features Stemma QT, making it easy to plug-in-play with any compatible Feather.

![lcds___displays_hero-boards.jpg](https://cdn-learn.adafruit.com/assets/assets/000/125/177/medium640/lcds___displays_hero-boards.jpg?1697426419)

You can press the red button to display deactivated nodes on screen.

The green button displays unlocked doors and random characters fill the screen while the rotary encoder adjusts the volume.

You can tilt the device to trigger different sound effects as if charging conduits in the game.

A special sound effect plays when the door is unlocked.

We think these features give it a bit more depth than your typical prop project.

Armed with a Faz-Wrench, you can help find Gregory and escape the ruins of Freddy Faz-bear's Mega Pizza-Plex.

## 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_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.

#  Faz-Wrench - Five Nights at Freddy's

## Code

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.

![lcds___displays_cp-code.jpg](https://cdn-learn.adafruit.com/assets/assets/000/125/173/medium640/lcds___displays_cp-code.jpg?1697426085)

https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/Faz_Wrench/code.py

## Upload the Code 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 RP2040 Prop-Maker Feather's **CIRCUITPY** drive.

- **lib** folder
- **faz\_sounds** folder
- **code.py**

Your RP2040 Prop-Maker Feather **CIRCUITPY** drive should look like this after copying the **lib** folder, **faz\_sounds** folder and the **code.py** file.

![CIRCUITPY](https://adafruit.github.io/Adafruit_Learning_System_Guides/Faz_Wrench.png )

## How the CircuitPython Code Works

The code begins by instantiating the LCD screen, accelerometer, and encoder over I2C. The two buttons are added to a `keypad` object.

```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

i2c = board.I2C()

int1 = DigitalInOut(board.ACCELEROMETER_INTERRUPT)
lis3dh = adafruit_lis3dh.LIS3DH_I2C(i2c, int1=int1)
lis3dh.range = adafruit_lis3dh.RANGE_2_G

ss_enc0 = Seesaw(i2c, addr=0x36)
enc0 = IncrementalEncoder(ss_enc0)

button = keypad.Keys((board.EXTERNAL_BUTTON, board.D13,), value_when_pressed=False, pull=True)

lcd = character_lcd.Character_LCD_I2C(i2c, lcd_columns, lcd_rows)
lcd.backlight = True
```

## Audio

The sound effects WAV files are imported from the **faz\_sounds** folder. Audio is output to the I2S amp on the Feather thru a Mixer object. The `open_audio()` function is used throughout the loop to open and play the sound effects.

```python
wavs = []
for filename in os.listdir('/faz_sounds'):
    if filename.lower().endswith('.wav') and not filename.startswith('.'):
        wavs.append("/faz_sounds/"+filename)
wavs.sort()
print(wavs)

audio = audiobusio.I2SOut(board.I2S_BIT_CLOCK, board.I2S_WORD_SELECT, board.I2S_DATA)
mixer = audiomixer.Mixer(voice_count=1, sample_rate=22050, channel_count=1,
                         bits_per_sample=16, samples_signed=True, buffer_size=32768)
volume = 0.5
mixer.voice[0].level = volume
audio.play(mixer)
wav_length = len(wavs) - 1

def open_audio(num):
    n = wavs[num]
    f = open(n, "rb")
    w = audiocore.WaveFile(f)
    return w
```

## NeoPixels

The NeoPixels are connected to the `EXTERNAL_NEOPIXELS` pin. The `pulse` animation is used.

```python
PIXEL_PIN = board.EXTERNAL_NEOPIXELS
BRIGHTNESS = 0.3
NUM_PIXELS = 8

PIXELS = neopixel.NeoPixel(PIXEL_PIN, NUM_PIXELS, auto_write=True)
pulse = Pulse(PIXELS, speed=0.001, color=RED, period=3)
```

## Generate a Puzzle

The `puzzle_string()` function generates a random series of letters and numbers to fill the LCD when the Faz Wrench is in puzzle mode. 

```python
def puzzle_string(length):
    _string = ""
    for _ in range(length/2):
        b = random.randint(0, 1)
        if b == 0:
            r = chr(random.randint(ord('A'), ord('Z')))
        else:
            r = str(random.randint(0, 9))
        _string += r
    _string += "\n"
    for _ in range(length/2):
        b = random.randint(0, 1)
        if b == 0:
            r = chr(random.randint(ord('A'), ord('Z')))
        else:
            r = str(random.randint(0, 9))
        _string += r
    lcd.message = _string
    return _string
```

## Keypad Events

The loop is checking for two things: a keypad `event` and if `puzzle` mode is active. The keypad events are tied to a `key_number`. If `key_number 0` is pressed, then `puzzle` mode is enacted. If `key_number 1` is pressed, then the value of `node_num` is increased by `1`. This updates text on the LCD.

```python
event = button.events.get()
    if event and event.pressed:
        number = event.key_number
        if number == 0 and not puzzle:
            pulse.fill(GREEN)
            puzzle = True
            lcd.clear()
            lcd.message = puzzle_msgs[2]
            wave = open_audio(1)
            mixer.voice[0].play(wave)
            while mixer.playing:
                pass
            puzzle_clock = ticks_add(ticks_ms(), puzzle_time)
        if number == 1:
            lcd.clear()
            node_num = (node_num + 1) % 5
            print(node_num)
```

## Default Mode

If `puzzle` is `False`, then the Faz Wrench is in its default mode. The LCD displays the text "`DEACTIVATED: 0 OF 4`", with `0` being the value of `node_num`. `node_num` increases with a button press. When `node_num` is greater than `3`, the text "`SECURITY BREACHED`" is displayed. The rotary encoder is used in this mode to control the volume of the sound effects.

```auto
if not puzzle:
        pulse.animate()
        mixer.voice[0].play(wave, loop=True)
        if node_num > 3:
            lcd.message = "SECURITY\nBREACHED"
        else:
            lcd.message = f"DEACTIVATED:\n{node_num} of 4"
        pos0 = -enc0.position
        if pos0 != last_pos0:
            if pos0 > last_pos0:
                volume = volume + 0.1
            else:
                volume = volume - 0.1
            volume = normalize(volume, 0.0, 1.0)
            mixer.voice[0].level = volume
            last_pos0 = pos0
```

## Puzzle Mode

In `puzzle` mode, the sound effect and NeoPixel color changes based on the orientation of the accelerometer. The LCD text displays random letters and numbers that are generated with the `puzzle_string()` function.

```python
if puzzle:
        x, y, z = [
            value / adafruit_lis3dh.STANDARD_GRAVITY for value in lis3dh.acceleration
            ]
        puzzle_string(lcd_columns*lcd_rows)
        if z > 0:
            wave = open_audio(2)
            print("playing up")
            pulse.fill(GREEN)
        else:
            wave = open_audio(3)
            print("playing down")
            pulse.fill(RED)
        mixer.voice[0].play(wave)
        while mixer.playing:
            puzzle_string(lcd_columns*lcd_rows)
            x, y, z = [
            value / adafruit_lis3dh.STANDARD_GRAVITY for value in lis3dh.acceleration
