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 ...

Library for PCF8574 Breakout Board by Testato on ArduinoForum, based on code from Mario H. You can see in the picture I2C_LCD_Breakoutboard.jpg the board compatible with this library. Without solder ...

A beginner-friendly Arduino project that measures distance using an ultrasonic sensor and displays the result on a 16x2 LCD using an I2C module. This project shows how to combine a sensor and a ...

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 ...

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, ...

Sometimes there’s just no substitute for the right diagnostic tool. [Ankit] was trying to port some I2C code from an Arduino platform to an ARM chip. When the latter code wasn’t working, he got clever ...
