If you run a local business like an electronics shop or a café, or if you just want to grow your online following and influence, this project is a fun way to help you keep track of your progress. A counter could also help contribute to growing your following if you hang it on the wall and actively ask your customers to like/follow you to see the numbers go up!
You’ve probably seen those social media follower counters that feature mechanical splitflap displays. In this project we’ll build a counter powered by RGB LEDs that scrolls through four social profiles, using APIs to pull the number of followers for each account. I’m using YouTube, Twitter, Facebook, and Instagram; you can, of course, tailor the project to your needs.
This project involves a bit of electronics, a bit of software coding, and a bit of woodwork, as well as some fairly advanced display work as we transfer a small portion of the Raspberry Pi’s HDMI output onto the LED matrices.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
