However, if you want a fixed contrast level then you can replace the potentiometer component with a resistor-diode setup as shown below. This gives a solid DC level (0.65/0.7 V) at the input of the Vo ...

[Tobie’s] part of the hack is to use an Arduino and a few buttons as the controller. It’s easy to set up and we think the breadboarded controller approximates the size and weight of an LCD ...

It powers the Arduino mini pro which drives the 1.8″ LCD screen and actuates the optoisolator which is responsible for triggering the camera.

The Alphanumeric LCD for Arduino will be our first circuit: using only one component, and of course the LCD, we can povide our Arduino board with at least a 16×2 alphanumeric LCD display that we will ...

This module will investigate creating an interactive side-scrolling game using an Arduino. It will also provide experience with advanced usage of the 16x2 LCD screen and its scrolling capabilities.
