At some point, I’ll be looking to extend my Raspberry Pi robot, and one of the ways to do that is to use I2C (Inter-Integrated Circuit) serial devices. So, in this feature, I look at how to access an Arduino board from the Raspberry Pi using this serial bus. I also include both Raspberry Pi and Arduino code to demonstrate the use of the serial interface. Continue reading “Using I2C Serial Bus to Connect Raspberry Pi to Arduino”
