Inter-Integrated Circuit (I2C) Protocol - Arduino Docs
The Wire library is what Arduino uses to communicate with I2C devices. It is included in all board packages, so you don't need to install it manually in order to use it. To see the full API for the Wire library, visit its documentation page .
Arduino and Stepper Motor Configurations
See the unipolar and bipolar motor schematics for information on how to wire up your motor. The stepper is controlled by with digital pins 8, 9, 10, and 11 for either unipolar or bipolar motors. The Arduino board will connect to a U2004 Darlington Array if you're using a unipolar stepper or a SN754410NE H-Bridge if you have a bipolar motor.

Getting Started with the Arduino TFT Screen
The Arduino TFT screen is a backlit TFT LCD screen with a micro SD card slot in the back. You can draw text, images, and shapes to the screen with the TFT library. The screen's pin layout is designed to easily fit into the socket of an Arduino Esplora and Arduino Robot, but it can be used with any Arduino board.
Servo Motor Basics with Arduino
Mar 4, 2024 · Servo motors have three wires: power, ground, and signal. The power wire is typically red, and should be connected to positive pole (+) of your power source. The ground wire is typically black or brown and should be connected to the negative pole (-) of your power source.
