ARDUINO BASICS #24 - I2C COMMUNICATION between two Arduinos
On day 24 of the Arduino Basics series, I'll show you how to make two Arduinos communicate with each other via the I2C interface. One Arduino is the master, the other the slave. In this example, we're using two Arduino Nanos. However, it works exactly the same way with Uno, Mega, and other Arduino models.
ATTENTION!!!
For those not using the LEDs from the advent calendar, you'll need to connect resistors to the LEDs (as shown in the circuit diagram in the video description).
The LEDs in the video have integrated resistors!
----------------
Arduino Basics is a video series in which I explain the fundamentals of programming to Arduino beginners. However, there might also be something interesting for more experienced makers among you. Feel free to take a look.
Since most tutorials focus on the technical aspects of Arduino projects, as a software developer, I've focused this series primarily on the software and programming.
