Arduino LCDs

An LCD is an electronic display module which uses liquid crystal to produce a visible image. The 16×2 LCD display is one of the most common modules used in DIY electronics and circuits. It can display 16 characters per line on 2 lines, making a total of 32 characters. Each character is displayed in a 5×7 or 5×8 pixel matrix, providing clear alphanumeric output. This display is widely used in embedded systems, Arduino, and microcontroller-based projects due to its simplicity and low cost.
