You have a microcontroller and two identical sensors, meaning that they have the same I2C address. Without a multiplexer or the possibility to configure the I2C address of the sensor you cannot attach ...

An Arduino library for I²C device operations. This is an abstraction class which can be used for all I²C devices to manage access at the register level. In addition to the device abstraction, it ...

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 ...

Refer below 16X2 LCD and I2C LCD interfacing With Arduino Tutorials- Visit for simillar projects at https://microdigisoft.com Tutorial 1: Arduino LCD Display Tutorial ...

There are two roles in the operation of I2C, one is “master”, the other is “slave”. Only one master is allowed and can be connected to many slaves. Each slave has its unique address, which is used in ...

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, ...

[Johngineer] found himself in need of an I2C sniffer, but didn’t have one available. Necessity is the mother of invention, so he put together this I2C sniffer sketch for Arduino. The arduino will ...

Arduino has just introduced three new Modulino modules: the Modulino Hub to support up to eight I2C devices (64 devices with 8 Hubs), the Modulino Extender to extend the I2C range to up to 30 meters, ...
