I built a box for my friend’s bar that has a Raspberry Pi inside and with the push of one button it streams audio to a website using Darkice and Icecast, while simultaneously lighting an ‘On-Air’ sign. I thought this was something people were already doing but after extensive searching I found nothing and decided to figure it out for myself and make this Instructable.
I used a Raspberry Pi 3+ B but as far as I can tell it would work on any Pi (perhaps the GPIO pin numbers would vary, I cannot attest to that though). I used the NOOBS package for the OS and bought a super simple soundcard for the input. I also added a safe shut-down button and activity LED to the box to protect the Pi.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
