Collection: LCD

An LCD (Liquid Crystal Display) is a technologically advanced flat-panel display that employs the unique light-modulating properties of liquid crystals, which don't emit light directly but rely on backlights or reflectors to generate color or monochrome images. Within the realm of LCDs, there are two primary types. The Character Display is designed mainly for displaying alphanumeric characters, commonly found in configurations like 16x2, allowing for 16 characters across two lines. Each character is shaped in a matrix of pixels, typically 5x8 or 5x10, making them ideal for devices such as calculators and digital clocks. On the other hand, the Graphic Display offers more individual control, enabling users to manipulate each pixel for displaying custom graphics or detailed text. These often come in resolutions like 128x64 or 128x32 pixels and can exhibit intricate designs or data visualizations. When we dive into the world of Arduino, an esteemed open-source microcontroller platform, it's reassuring to note its seamless compatibility with both these LCD types. Libraries such as the LiquidCrystal for character displays and Adafruit GFX for graphic displays make interfacing straightforward. Most LCDs connect to Arduino through parallel or serial communication pathways like I2C or SPI, demanding only a few GPIO pins for data transfer and control purposes. Given their affordability, ease of connection, and the abundance of online resources, LCDs are a favorite among Arduino enthusiasts, be it for simple textual outputs or complex graphic illustrations.
