The wiring diagram below shows you how to connect the MAX7219 LED dot matrix display to the Arduino.Note that when using the MD_Parola library, you need to orient the display with the DIN connector on the right, otherwise the text will be printed upside down.For more information seethe sect...
LED dot matrix. Small OLED Graphics displays. If you're looking for a simple way to output text from an Arduino a good choice is an HD44780 LCD display, but you usually need about 8 pins which may be a bit too much for some designs. One option is to use an I2C based HD44780 mean...
