Prompt Title: Connect Adafruit Speaker Raspberry Pi

To connect an Adafruit speaker with a Raspberry Pi 3, you will need to follow these steps:

1. First, make sure you have all the necessary hardware. You will need an Adafruit Steema Speaker, a Raspberry Pi 3, and some jumper wires.

2. Connect the speaker to the Raspberry Pi 3 using jumper wires. The speaker should have four pins: VCC, GND, OUT+ and OUT-. Connect the VCC pin to the 5V pin on the Raspberry Pi 3, the GND pin to the GND pin on the Raspberry Pi 3, the OUT+ pin to GPIO 18 (Pin 12), and the OUT- pin to GPIO 23 (Pin 16).

3. Power on your Raspberry Pi 3 and log in to the operating system.

4. Open a terminal window on your Raspberry Pi 3 and type the following command to install the necessary software:

   arduinoCopy code
   sudo apt-get install python3-pip
   sudo pip3 install RPi.GPIO adafruit-blinka
   

5. Once the software is installed, you can test the speaker by running the following Python code in the terminal:

   pythonCopy code
   import board
   import digitalio
   import audioio
   
   speaker_enable = digitalio.DigitalInOut(board.D18)
   speaker_enable.direction = digitalio.Direction.OUTPUT
   
   speaker = audioio.AudioOut(board.D18)
   
   # Play a sound
   with open("example.wav", "rb") as f:
       wave = audioio.WaveFile(f)
       speaker.play(wave)
       while speaker.playing:
           pass
   

   Note: Replace "example.wav" with the file name of the audio file you want to play.

6. If you can hear sound from the speaker, then you have successfully connected your Adafruit Steema Speaker with your Raspberry Pi 3!
