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 ...

When you connect a standard LCD to an Arduino, you’ll notice that it consumes a lot of I/O pins. In 4-bit mode, it typically uses six or more connections, leaving fewer pins for other sensors or ...

Arduino library for the I2C LCD display, typical 20x4 characters. The library is inspired by the excellent New-LiquidCrystal library by F. Malpartida. Therefore the interface is kept quite identical, ...
