Normally driving an LCD requires seven connections to pins on the display, but by using a shift register, [Phillip Warner] at Arduino Playground was able to drive an LCD using only 3 wires.

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

we can povide our Arduino board with at least a 16×2 alphanumeric LCD display that we will use in all our future applications. This project consumes only three I/O pins, no matter what we decide to ...

A small LCD screen can be extremely helpful with small ... like [Fabien] did with his animated Arduino progress bar. (Google Translate from French) The project started out simply enough: all ...

Power comes from the underlying Arduino, and when the display is attached there is still access to all 54 Arduino pins on the top side of the board. “Without any extra wiring, the display shield ...
