A practical guide to wiring a small I2C OLED to an Arduino, including a warning about setting the display address correctly.
Praised as a visual walk-through of the I2C protocol, driving the bus by hand so each clock and data transition can be seen.
Offered as a tutorial on linking two Arduinos as master and slave, though viewers question the way it shares power between the boards.
