Understanding the LCD I2C ModuleThe LCD I2C module is a combination of a standard liquid crystal display (LCD) and an I2C interface. This setup allows for simplified wiring and communication between the display and microcontrollers like Arduino. Typically, these modules are available in 16x2 or 20x4

IntroductionUsing LCDs with Arduino can significantly enhance your projects, allowing for dynamic displays of information and user interaction. However, many beginners encounter common pitfalls that can lead to frustration and wasted time. This comprehensive guide will highlight these mistakes and p

Understanding the PCF8574 I2C LCD ModuleThe PCF8574 is an I2C I/O expander that allows you to control multiple devices using only two wires: SDA (data line) and SCL (clock line). This is particularly useful when working with LCD displays, as it reduces the number of pins required on your microcontro
