HD44780 Dot Matrix LCD Controller Library This is a weekend project naive arduino library made for HD44780 controller based lcd's. It abstracts the complexity of directly interacting with the LCD's ...

The Dot Matrix Display When we are talking about the MAX7219-based dot matrix display module, it consists of 64 LEDs connected in a row-column format so that we could easily control them with the ...

The dot matrix clock was built without the use of a regular Arduino board but uses the ATmega168 with Arduino bootloader and assembled on a breadboard. An RTC clock compensated by temperature is used ...

Messages are composed on an old PS/2 keyboard through an Arduino and a 16×2 LCD display, and punched onto the tape a dot at a time. The punch is a large darning needle riding on the remains of an ...
