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 ...

The most difference to the original LiquidCrystal library from Arduino is that this library supports printf() functionality. When using PlatformIO and AVR, to support float you must add following line ...

The I2C (Inter-Integrated Circuit) bus is a synchronous serial communication protocol that allows multiple electronic components (sensors, displays, memories, etc.) to be connected within the same ...

Most 16x2 and 20x4 LCD modules with an I2C backpack use a PCF8574 I/O expander to communicate with a microcontroller over the I2C bus. Many tutorials use the default I2C address and do not explain ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...
