PI4J-Arduino-I2C-Connection A coding-example on how to send data between an Arduino and a Raspberry Pi over I2C-bus using PI4J I had a lot of problems and issues while developing a project like ...

Run the I2C_address_finder.ino file after connecting I2C to arduino to get the address of I2C on the Serial Monitor because if the address is correct then connection cannot be established properly.

You can use them with LCD modules that have a HD44780 compatible interface with various screen sizes by attaching to the back of the LCD module. This allows connection to your Arduino (or other ...

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, ...

The DS3231 RTC module code development involves initialising the I2C connection, publishing the current time, and retrieving time data for your applications Installing Arduino DS3231 RTC Library ...

[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 … ...

Some resistors were added to protect I/O pins of the Arduino. For the I2C bus we rely on the open drain structure to tackle the 5V <->3.3V issue of the Gnublin I2C boards, after all this shield is ...

Once again in this project i used the Raspberry PI 0 W. The other part of the project is an Arduino Uno connected to the Sparkfun Bluetooth "Mate Silver" module. First thing to do is to configure your ...
