SparkFun Qwiic Alphanumeric Display
SparkFun Qwiic Alphanumeric Displays are fourteen-segment digits that allow for displaying numbers, characters, and symbols. The SparkFun Alphanumeric Display Arduino library makes printing strings to the display as easy as calling the print() function. Use the library to send I2C commands to the HT16K33 LED driver chip to light up segments. This includes the decimal point or colon and even scrolling a string across the display.
