Simple code for creating a music player with variable switches. Each switch (door knob, squeeze mechanism, etc.) will trigger a different song.
A Samba file server allows user to upload songs to the Pi.
After installing Raspian OS on an SD Card and setting up WiFi(https://www.raspberrypi.org/learning/software-guide/), download the Adafruit Stereo Speaker Bonnet from https://learn.adafruit.com/adafruit-speaker-bonnet-for-raspberry-pi?view=all.
Adafruit's simple install link is:
curl -sS https://raw.githubusercontent.com/adafruit/Raspberry-Pi-Installer-Scripts/master/i2samp.sh | bash
Open Terminal on the Raspberry Pi and go to the home directory cd ~.
Download this repo by typing git clone https://github.com/olliebck/switchmusicbox.
Move into the directory cd /home/pi/switchmusicbox and create an empty directory with mkdir songs.
Install Samba and edit the config file to link to this directory.
Step 1: Install Samba
sudo apt install -y samba
Step 2: Edit Config File
sudo nano /etc/samba/smb.conf
Add below at the end of the smb.conf file:
[musicbox songs]
comment=musicbox share
path=/home/pi/switchmusicbox/songs
browseable=Yes
writeable=Yes
only guest=No
create mask=0740
directory mask=0750
public=no
Step 3: Create Sign-In
sudo smbpasswd -a pi
Add password when prompted.
After setting up Samba, go to Mac/PC computer to access shared drive and upload songs into the "Songs" folder by dragging in ".wav" audio files.
Attach a switch to GPIO pin 13 and GND on Raspberry Pi/Speaker Bonnet.
In Terminal on the Pi, change directories into the directory with musicbox.py:
cd /home/pi/switchmusicbox
Test out the switch by running the program.
sudo python musicbox.py
If music plays when you hit the switch, and cycles to new songs, super (make sure you have WAV audio files in the Songs directory). Add the script to run on startup by changing the rc.local file found in /etc. Here we use the "nano" editor:
sudo nano /etc/rc.local
And adding above the "exit 0" line:
sudo python /home/pi/switchmusicbox/musicbox.py &
Reboot the pi and see if script runs on startup.
If it does, edit code and hardware to account for additional switches. GPIO 18, 19, and 21 are taken up by the Bonnet.
