Say goodbye to the low-tech days of rubber duck debugging! Duckveloper 🐤 is the coding partner you never knew you needed.
Simply press a button and the innovative, high-tech duck will generously provide you with words of "encouragement" to help you figure out what's really wrong with your code.
Arduino project with an MP3 shield, speaker, and rubber duck. Inspired by the strategy of rubber duck debugging.
This project uses the Arduino VS1053 Library to decode MP3 audio and interface with the MP3 shield.
| Serial | Name | Quantity | Description |
|---|---|---|---|
| 🐤 | Rubber Duck | As many as you need to be happy in life | |
| DEV-11021 | Arduino Uno - R3 | 1 | |
| DEV-12660 | SparkFun MP3 Player Shield | 1 | Requires soldering on headers |
| PRT-11417 | Arduino Stackable Header Kit - R3 | 1 | For the MP3 Shield |
| BOB-11044 | SparkFun Mono Audio Amp Breakout - TPA2005D1 | 1 | Requires soldering connections |
| COM-09151 | Speaker (0.5W) | 1 | |
| PRT-10512 | Optional: 9V Battery Holder | 1 |
Other common generic components you should have:
- 1 button/switch (e.g. Momentary Pushbutton Switch)
- 1 LED, bright enough to shine through the duck's plastic (e.g. Super Bright LED)
- 1 breadboard
- Resistors (1 x 330 Ω, 1 x 10k Ω)
- Wires
Solder the stackable headers onto the MP3 Player shield.
Mount the MP3 Player shield onto the Arduino Uno.
Connect the remaining components according to the following schematic:
To accurately connect the Audio Breakout Board (TPA2005D1), follow the SparkFun Mono Audio Amplifier Quickstart Guide.
Use a hobby or utility knife to (carefully!) cut a small hole in the duck's rear end.
Insert the LED into the hole so it will light up the duck when a voiceline is playing.
Apologize profusely throughout the procedure.
Format the SD card to FAT16 or FAT32.
Place your intended voicelines onto the SD card, named in the format of track001.mp3, track002.mp3, etc.
Install the SD card into the MP3 Player Shield.
Install the VS1053 library in the Arduino IDE.
Open the duckveloper/duckveloper.ino program. Modify the value NUMBER_OF_TRACKS (location in code here) accordingly, if you have changed the number of voicelines on the SD card.
Compile and upload the project to the Arduino.
Press the button to trigger one of the random voicelines as well as the LED.
To monitor the program's output, open the serial monitor and set the baud rate to 115200.
