how to run radio automation software on raspberry pi

However, the 3B+ does not offer any significant advantages for this setup and requires more power. You can also use the 2B if you do not need WiFi or Bluetooth, or the 3B+. The heart of this media center is the affordable but powerful 3B, it can handle multiple audio and video players with its quad core processor and 1 GB RAM. So for this specific example, two individual Amp HAT setups can be selected based on the rooms' individual challenges and opportunities. You need one Raspberry Pi Amplifier HAT bundle setup for each room. You can compare the different Amp HATs in our comparison chart to find the right fit for your multiroom zones. These sound cards are called Amp HATs (Hardware Attached on Top) and come in different varieties. Based on the intended scope of your setup, you can add or remove as many players as you want.Ī combination of digital-analogue-converter and amplifier makes the most sense for rooms without pre-existing audio components.

Here, we will assume the basic setup using one set of speakers for each room. Power up the Pi and head to the command-line either via SSH or by directly logging into the device.The required items for this system may vary, depending on how big you want your multiroom setup to be. Please check your local regulations before attempting this project. Even without the wire, the FM signal broadcast by the Raspberry Pi will be picked up by nearby FM receivers.Ī word of caution: The laws for broadcasting FM signals varies from country to country.

To transmit a surprisingly strong FM signal, all you need is to attach a wire to the GPIO 4 pin. These interfaces are not plug-and-play but can controlled through software. These General Purpose Input/Output (GPIO) “ports” are the 26-pins (arranged in a 2×13 strip) you see on the board. Besides the familiar Audio, Ethernet, HDMI, and USB ports on the Raspberry Pi, the device also has interfaces that are designed to to connect more directly with other chips and modules. A bunch of folks over at Code Club pihack wrote a program to use hardware on the Raspberry Pi that’s meant to generate spread-spectrum clock signals to instead output FM Radio signals.
