# Pico Dog
Detects motion and plays a dog bark sound when it's dark.
**Special Halloween Edition:** https://github.com/andruhon/pico-dog/tree/halloween-edition
See [PROJECT.md](PROJECT.md) for a detailed project writeup with build instructions and real-world performance notes.
See [materials.md](materials.md) for the list of materials used.
See [circuit.md](circuit.md) for circuit details.
## Audio Sources
Dog bark sound:
[Dog Bark by abhisheky948](https://freesound.org/people/abhisheky948/sounds/625498/) (Distributed under CC0 license)
## Installation
### Development Environment (Optional)
If you need to work with the project files locally, you can create a Python virtual environment:
```
python -m venv venv
source venv/bin/activate
python -m pip install -r requirements.txt
```
### Dependencies
This package uses the following packages as dependencies:
* https://github.com/CoreElectronics/CE-PiicoDev-Unified/blob/main/PiicoDev_Unified.py
* https://github.com/CoreElectronics/CE-PiicoDev-VEML6030-MicroPython-Module/blob/main/PiicoDev_VEML6030.py
* https://github.com/joeky888/awesome-micropython-lib.git
* https://github.com/danjperron/PicoAudioPWM.git
### Deploying to Pico
**Prerequisites:** MicroPython must already be installed on your Raspberry Pi Pico. Installation instructions can be found at https://micropython.org/download/RPI_PICO/
**Note:** Connecting to Raspberry Pi Pico on Linux may sometimes be challenging. Check [linux.md](linux.md) for troubleshooting tips.
**mpremote documentation:** https://docs.micropython.org/en/latest/reference/mpremote.html
Install dependencies to Pico:
```bash
mpremote mip install github:CoreElectronics/CE-PiicoDev-Unified/PiicoDev_Unified.py
mpremote mip install github:CoreElectronics/CE-PiicoDev-VEML6030-MicroPython-Module/PiicoDev_VEML6030.py
mpremote mip install github:joeky888/awesome-micropython-lib/Audio/chunk.py
mpremote mip install github:joeky888/awesome-micropython-lib/Audio/wave.py
mpremote mip install github:danjperron/PicoAudioPWM/myDMA.py
mpremote mip install github:danjperron/PicoAudioPWM/myPWM.py
mpremote mip install github:danjperron/PicoAudioPWM/wavePlayer.py
```
Copy sources to Pico:
```bash
mpremote fs cp -r src/* :
```
Verify installation:
- Run `mpremote ls` to make sure everything is copied over (you may need to restart the Pico to pick up changes)
- Run `mpremote df` to check available space on the Pico
## Custom Sounds
When using your own sounds, make sure they are **16-bit WAV files with a 16000 Hz sample rate**. You can use [Kwave](https://apps.kde.org/kwave/) (open source audio editor) to convert files.
**Recovery:** If you copied a corrupted file and your Pico seems to be bricked, you can flash it with the official Raspberry Pi memory reset: [flash_nuke.uf2](https://www.raspberrypi.com/documentation/microcontrollers/pico-series.html#resetting-flash-memory)
