You could use the bluetooth function like this: Get a Micro USB to USB adapter and a USB BlueTooth adapter (here and here); Connect the adapter the the Pi's Micro USB port (the one labeled USB, not PWR) and the dongle to the USB port on the adapter; Update Raspbian with `sudo apt-get upgrade && sudo apt-get dist-upgrade` as the newest version contains a ...

The Adafruit board you've linked to is just a DAC and amp bundled together. From your linked page: It takes standard I2S digital audio input and, not only decodes it into analog, but also amplifies it directly into a speaker. I've tested most of the audio output options from the Pi, and pretty much everything aside from the analogue output is OK. I've ...

I have a Pi Zero Wireless running Raspbian Jessie Lite (4.4.50+) with a pHAT DAC. I ran the automated install - curl https://get.pimoroni.com/phatdac | bash At the end of running this script it asked me if I wanted to test it, (yes), and it successfully played the sounds through the headphones I had attached. Running aplay -l gives me the same output as ...

This page says: The pHAT DAC provides a high-quality digital to analog audio converter for the Raspberry Pi: 24-bits at 192KHz via the I2S interface on the 2x20 pin GPIO header. According to this description and the image of the pinout as shown there the pHAT-DAC only uses the GPIO pins tied to the I2S interface, specifically the pins 18, 19, and 21 (BCM ...

My solution: I got the adafruit speaker bonnet instead My plan is to add resistors before the one mono 8ohm 0.5 watt speaker so that the power does not exceed that of the speaker, my plan is also to do the same for the headphones, and hopefully they work. I would need a big resistor, but I have a pack from radio shack lol Formulas used V=IR P=IV P=V^2/R

As it says in bold print on the Adafruit page: This updated design fits perfectly onto the Pi Zero, Pi 3, Pi 2 or Model A+, B+! (Any Pi with a 2x20 connector) This is because all 40 pin models have the exact same pinout, just as all 26 pin models have the exact same pinout. So if you find a hat intended for the Pi that has a 40 pin plug, it is ...

You should use a systemd unit file to run a program at startup. Try this simple Unit to start with your project. If it runs on bootup you can improve it step by step. Create a new service with rpi ~$ sudo systemctl --force --full edit my-startup-song.service In the empty editor insert these statements, save them and quit the editor: [Unit] Description=...

To execute a command at system startup, without the need to login, so you don't need a screen at all, edit the file /etc/rc.local. sudo nano /etc/rc.local Paste any command there, and make sure the file end with exit 0. Also make sure to use the full path to link your audio file. #!/bin/sh -e aplay /home/pi/Music/noise.wav exit 0 aplay is a ...

Yes, use a shell script, that triggers your favorite mp3 wav player via command line.., you can customize a script file to do all sorts of nifty commands like cycle through all tracks.. and have that script load up in an rc.local file to trigger at startup. Lots of ways you can do this, I'm sure you might be able to load a gui based player via command line ...
