Flip-Dot Clock / Display HD

This flip-dot display is controlled using an Arduino via custom made controller boards. The controller boards include: - 74HC595 shift registers - NPN transistor arrays (ULN2003A) - PNP transistors (BC327) - 1kohm base resistors for the PNP transistors (current limiting resistors) This flip-dot display is mainly used as a clock, but it can also be used to display text or images/animations streamed over serial. The modes that this display currently supports are: 1. Clock Mode: 12-hr / 24-hr time, date, year 2. Text Mode (streamed from a PC over serial) 3. Image / Animation Mode (streamed from a PC over serial) 4. Random Mode 5. Demo Mode: Displays a few test patterns 6. ASCII Mode: Displays all the supported ASCII characters Time is kept using a TinyRTC module Music: Entrepreneur by Scott Holmes Green Fields by Scott Holmes
