Zeroconf (aka Bonjour, very rarely Rendezvous) is a group of technologies to “automagically” discover systems and services on a local area network.
With the proliferation of embedded, networked Raspberry Pi projects, it can be a chore to keep track of numeric IP addresses for each. Dynamically-assigned addresses (via DHCP) can further confuse the issue.
Zeroconf helps by assigning the system a name (e.g. raspberrypi.local instead of 192.168.0.42). It can then be easily accessed from other computers on the local network…provided they’re also running Zeroconf!
Mac OS X and BeagleBone Black already support Zeroconf. For other systems, here’s how to set that up…
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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
