In this project, you can connect RGB LED Board to Raspberry Pi Model B+ and with the help of Kaa-enabled application program it to display twitter messages with a particular hash tag or mention. It acts like a feed to display tweets which interest you and you can specify the speed of the feeds displayed and how often. Such a board can also be used to display ads to target a certain set of people.
Let’s see, how you can do this at home.
You need 16×32 RGB LED Board, 3 74AHCT125 quad level shifter, RPI, a breadboard and a lot of wires; whose specifications you can get from the link, given below. We will give you a heads up here, there is going to be a lot of wiring to be done. You can follow the Adafruit tutorial to wire your RPI to the LED Board. But the complete wiring scheme can be seen below.
You can read about the libraries used and the software code, to make this functional, in the link below and you’re good to go.
