// This example demonstrates how to control a real-world Stepper Motor using HomeSpan's
|
|
// generic StepperControl Class.
|
|
|
|
// For this sketch we will use an implementation of StepperControl designed to operate an
|
|
// Adafruit TB6612 1.2A DC/Stepper Motor Driver Breakout Board (https://www.adafruit.com/product/2448)
|
|
// using only its 4 control pins: AIN1, AIN2, BIN1, and BIN2
|
|
|
|
// See HomeSpan's StepperControl documentation for a list of built-in driver boards, as well as for
|
|
// detailed instructions on how you can easily use StepperControl to implement a custom driver for any board.
|
|
|
|
// Note this example is based on the fully-commented WindowShade Accessory sketch from Tutorial Example 13.
