This video attempts to describe how to connect an Arduino to the HT1622 or compatible LCD driver chip.  The LCD is recovered from a treadmill and is a just-for-fun project as Ive no real purpose for the LCD.  The LCD has 15 digits each having 14 segments and the decimal point segment.  

I'm using a modified version of MartyMacGyver's code https://github.com/MartyMacGyver/LCD_HT1622_16SegLcd and Ive produced schematics and a spreadsheet to work out the 14 segment font available at https://github.com/happymacer/pf906-LCD-display.
