This video is the second of 2 videos that attempts to describe how to connect an Arduino to the HT1625 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 285 separate elements and I discuss how to access each element.

I'm using a modified version of MartyMacGyver's code https://github.com/MartyMacGyver/LCD_HT1622_16SegLcd and Ive produced schematics and a LCD setout spreadsheet available from my Github: https://github.com/happymacer/pf906-LCD-display.
