This poses a problem – although I’ve configured the WiFi, I’m using DHCP and therefore don’t know what IP the Pi will be using when it boots! Without this information, I can’t SSH into the device or connect to my project remotely. I therefore needed a way to have the Pi inform me of its IP address on boot.
My solution: display the IP address on the Unicorn pHAT LED matrix in binary! Not only is this practical, but it also boosts my geek cred 😉
In this tutorial, I’ll walk you through how to replicate this solution for your own projects.
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!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
