Libraries

JLed

JLed is an Arduino library to control LEDs. It uses a non-blocking approach and can control LEDs in simple (on/off) and complex (blinking, breathing) ways in a time-driven manner.

log4arduino

A lightweight, no-frills logging library for Arduino & friends.

LOG("hello, log4arduino.");
LOG("use %s formatting: %d %c %d %c %d", "printf", 9, '+', 1, '=', 10);

Colorduino RGB matrix driver

Driver for 8x8 RGB LED matrix.

• see wiki for detailed information

CJMCU-8x8 RGB matix

An 8x8 LED RGB matrix based on WS2812 "NeoPixels".

WEMOS D-Duino

The Wemos D-Duino is a ESP8266 board with an integrated SSD1306 OLED display connected via I2C.
