# PropMaker Jack O'Lantern
## Overview
https://youtu.be/-EdjjKkbZP8
Turn an IKEA Pumpkin LED lamp into a distance sensing Halloween prop that plays music and sound effects! A continuous servo rotates the pumpkin as spooky laughter blasts from the 3D printed base. Perfect for greeting your guests at Halloween parties or scaring treat or treaters.
The [KUSTFYR LED table lamp from IKEA](https://www.ikea.com/us/en/p/kustfyr-led-table-lamp-pumpkin-70560309/) features a bright LED bulb with a pumpkin themed lamp shade that has two screen printed faces. This project utilizes the stock LED bulb and pumpkin, brought to life with the Adafruit PropMaker Feather RP2040 and CircuitPython code.
A VL53L1X time of flight sensor is hidden inside the base that detects when an object is nearby. Different audio is played depending on the distance, making this an advanced prop that's more than just a typical store-bought Halloween amusement.
You may customize the CircuitPython code to change the distances, servo movement, sound effects and more.
The 3D printed base features unique details that are inspired by gothic architecture. The parts are designed to snap fit together and are printed without any support material, making for an IKEA-esque assembly.

# PropMaker Jack O'Lantern
## 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.
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.

# PropMaker Jack O'Lantern
## Code the Jack O'Lantern
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/Spinning_Ikea_Pumpkin/code.py
## Upload the Code, Sound Effects and Libraries to the Feather RP2040 Propmaker
After downloading the Project Bundle, plug your Feather RP2040 Propmaker 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 Propmaker's **CIRCUITPY** drive.
- **lib** folder
- **code.py**
- **happy-halloween.wav**
- **laught-1.wav**
- **laught-2.wav**
- **laught-3.wav**
- **music-loop-1.wav**
- **music-loop-2.wav**
- **music-loop-3.wav**
Your Feather RP2040 Propmaker **CIRCUITPY** drive should look like this after copying the **lib** folder, sound effects and the **code.py** file.
## How the CircuitPython Code Works
At the top of the code, there are some user configurable settings that you can edit. `distance_delay` affects how often the time of flight sensor is read. The `servo_delays` array has four different delay amounts for spinning the servo. These correspond with the distances in the `distances` array. In the loop, when you pass certain distances with the time of flight sensor, the delay for the servo changes.
Finally, the music and sound effect audio files are opened. You can change which music loop and sound effects you want to have for the project. A few options are included in the project bundle.
```python
distance_delay = 4 # how often vl53 is read
servo_delays = [2.0, 1.5, 1.0, 0.5] # servo spin delay
distances = [150, 100, 80, 40] # in centimeters
max_audio = 1
# audio files
music = audiocore.WaveFile(open("music-loop-1.wav", "rb"))
fx_1 = audiocore.WaveFile(open("happy-halloween.wav", "rb"))
fx_2 = audiocore.WaveFile(open("laugh-2.wav", "rb"))
fx_3 = audiocore.WaveFile(open("laugh-3.wav", "rb"))
```
## I2C and Audio
The time of flight sensor is instantiated over I2C. Next, the I2S audio is instantiated followed by a mixer object. Each of the four audio files will be played on separate voices.
```python
i2c = board.STEMMA_I2C()
vl53 = adafruit_vl53l1x.VL53L1X(i2c)
tracks = [music, fx_1, fx_2, fx_3]
audio = audiobusio.I2SOut(board.I2S_BIT_CLOCK, board.I2S_WORD_SELECT, board.I2S_DATA)
mixer = audiomixer.Mixer(voice_count=4, sample_rate=22050, channel_count=1,
bits_per_sample=16, samples_signed=True)
audio.play(mixer)
mixer.voice[0].play(tracks[0], loop=True)
mixer.voice[0].level = 0.0
```
## Input, Output and PWM
The external power pin is enabled as an output. This gives power to the external components on the Feather. The slide switch is attached to the `EXTERNAL_BUTTON` pin. In the loop, the slide switch controls the state of the external power pin. A PWM object is setup for the `EXTERNAL_SERVO` pin for the continuous servo.
```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
switch = DigitalInOut(board.EXTERNAL_BUTTON)
switch.direction = Direction.INPUT
switch.pull = Pull.UP
# servo control
pwm = pwmio.PWMOut(board.EXTERNAL_SERVO, duty_cycle=2 ** 15, frequency=50)
servo = servo.ContinuousServo(pwm, min_pulse=750, max_pulse=2250)
```
## The Loop
In the loop, if the time of flight sensor does not detect anything in front of it, the mixer and servo are paused. If the sensor detects something, `lamba` is used to calculate which value in distances that the reading is closest to. This result determines the sound effect played and the servo speed.
```python
while True:
if switch.value:
external_power.value = True
if prop_time:
if ticks_diff(ticks_ms(), servo_clock) >= servo_time:
print(servo_throttle)
servo.throttle = servo_throttle
servo_throttle = not servo_throttle
servo_clock = ticks_add(servo_clock, servo_time)
if ticks_diff(ticks_ms(), vl53_clock) >= vl53_time:
if vl53.data_ready:
print(f"Distance: {vl53.distance} cm")
vl53.clear_interrupt()
if vl53.distance is None:
prop_time = False
mixer.voice[0].level = 0.0
servo_time = int(servo_delays[0] * 1000)
servo.throttle = 1.0
else:
closest_distance = min(distances, key=lambda x: abs(vl53.distance - x))
# print(closest_distance)
if vl53.distance <= distances[0]:
prop_time = True
mixer.voice[0].level = max_audio
else:
prop_time = False
mixer.voice[0].level = 0.0
servo.throttle = 1.0
if closest_distance == distances[1]:
mixer.voice[1].play(tracks[1], loop=False)
servo_time = int(servo_delays[1] * 1000)
elif closest_distance == distances[2]:
mixer.voice[2].play(tracks[2], loop=False)
servo_time = int(servo_delays[2] * 1000)
elif closest_distance == distances[3]:
mixer.voice[3].play(tracks[3], loop=False)
servo_time = int(servo_delays[3] * 1000)
vl53_clock = ticks_add(vl53_clock, vl53_time)
else:
external_power.value = False
```
