Open Watch Winder

This code allows you to control a stepper motor with a momentary switch button.

Using the Winder

On powerup, the LED will fade on an the winder will be in standby, waiting for a button press.

The button knows two types of inputs:

• press, which is input shorter than 500ms
• long-press, which is input longer than 500ms

The winder works in cycles, which means it will do the configured number of cycles (CYCLES), with each cycle consisting of a configured number of rotations in each direction (ROT_R, ROT_L), then wait for the configured amount of minutes (PAUSE_MIN), and eventually restart the cycles. This will be refered to as "winding".

In short:

• press the button to start winding
• long-press the button to stop winding

Switching Modes

• When pressing the button while the winder is in standby, it will start winding.
• When long-pressing the button while it is winding, it will return to the home position and stop winding.
• When long-pressing the button while it is waiting for the next cycle, it will stop winding.
• When pressing the buttong while it is waiting for the next cycle, it will start winding.

LED Status

• Solid: Standby
• Blinking (1s on, 0.5s off): Winding
• Slow Breathing: Waiting for next cycles
• Fast Breathing: Next cycle will start in <1 minute
