This library is to use an HC4067 multiplexer by means of a PCF8574 (I2C 8 channel IO). The HC4067 allows e.g one analog port read up to 16 different analog channels, or one digital port to read the ...

I2C_SCANNER is a class to build an I2C scanner, either minimal or more complex. The class provides different functions to analyse the connectivity of devices on the I2C bus. There are functions to ...

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 ...

The venerable I²C bus has never been more popular. Most modern microcontrollers either have a hardware I²C interface or are capable of bit-banging one in software. Many sensors, AD and DA converters, ...

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 ...

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, ...

Le vénérable bus I²C n’a jamais été aussi populaire qu’aujourd’hui. La plupart des microcontrôleurs modernes possèdent une interface matérielle I²C ou permettent son implantation logicielle, et de ...

In this guide, we will create a simple and precise digital clock using the Raspberry Pi Pico RTC DS3231 Module through the Arduino IDE. We will use a 16x2 I²C LCD screen to display the information.
