Come and meet the XIAO, a tiny 32-bit Arduino-compatible microcontroller that goes for only 5 dollars!
This amazing little device outperforms the Arduino AVR boards and offers features like an analog output and 10 PWM pins.
We will explore the XIAO using the Arduino IDE and see how easy it is to use.
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.
