This is the first of a series of articles about using I2C. Today I will explain what I2C is and show you the Arduino Wire Library
We will run two demonstrations. The first demo will show you how to exchange data between two Arduinos using I2C. The second demo will describe how to control an LED on a slave Arduino with a potentiometer on a master.
Web Site Updates
I am applying several updates and improvements to the website this week, and you may notice some “odd behavior” on a few pages while the changes are being performed.
Please feel free to continue to use the website during these upgrades. The changes that I am making will (hopefully) make the website a more useful resource for you.
