RGB matrix displays time and environmental data


Temperature, humidity, and ambient pressure are the key parameters for environmental monitoring. With the advent of MEMS and integrated multi-sensor technologies, it’s been feasible to miniaturize environmental sensors and embed them into portable electronics. BME280 is one such fully integrated environmental unit from Bosch that combines sensors for pressure, humidity, and temperature in a tiny 8-pin metal-lid LGA package of size 2.5 x 2.5 x 0.93 mm³. This article describes how to read the environmental data from BME280 using Arduino and display the data on a 16×32 RGB matrix panel using the RGB driver shield. Things you will need Following items are used

16×32 RGB Matrix Panel Driver Shield Revision 1


Our RGB matrix panel driver shield for Arduino Uno has been slightly revised. The shield now also carries the DS1307 RTC chip on board along with a CR1220 coin cell battery holder on the back. It is applicable for driving popular 16×32 RGB matrix panels with HUB75 (8×2 IDC) connectors. Row and column driver circuits are already built on the back side of these matrix panel. The data and control signal pins for driving rows and columns are accessible through the HUB75 connector. It requires 12 digital I/O pins of Arduino Uno for full color control. The revised version also has a slide

Hookup guide for 16×32 RGB LED panel – Part 3


In this third part of the 16×32 RGB LED panel hookup guide, we will run some demo sketches with Arduino Uno to display basic text and animation on the 16×32 RGB LED matrix. These demo programs use Adafruit’s RGBMatrixPanel Library are found inside its Example folder. The wiring between the RGB panel and Arduino Uno is discussed in detail in the previous parts of this 3-part tutorial.
