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 described. So I decided to put the ...

For testing I've used the Arduino nano to emulate two devices, one I2C photoresistor sensor and one SPI PWM LED. These devices, for example, could be two different attiny85; but as the atmega368p is ...

In our previous tutorial learned about SPI communication in Arduino. Today we will learn about another Serial Communication Protocol: I2C (Inter Integrated Circuits). Comparing I2C with SPI, I2C has ...

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 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 ...
