Big update! The stepper controller firmware has reached a stable, working state — and I’m happy to report that all major features are now live and tested!

✅ Core Features Now Working

Here’s what’s running smoothly:

• CW (Clockwise) Mode – Tap the encoder, and the motor rotates smoothly in one direction.

• CCW (Counter-Clockwise) Mode – Same deal, but in reverse!

• ARC Mode – The star feature. Users define the left and right limits using the Auxillary buttons. Once saved, the motor oscillates smoothly between the two ends.

• Play/Pause – Pressing the encoder switch now pauses or resumes the motion, regardless of mode. Super intuitive.

• Non-Volatile Memory – The system now remembers the last mode and positions even after power-off. This makes it ideal for installations or embedded setups — set it once and forget it.

🧠 How It Works for the User

1. Choose your mode (CW, CCW, ARC) while the motor is paused.

2. In ARC mode, press the Aux buttons and rotate to set endpoints, then press the Save/Erase Button to save the position. 

3. Press the play button to start motion.

4. Pause or play any time with a single click.

5. Power it off and on — your config is still there!

🧪 What’s Next?

• Implement I2C daisy-chaining for multiple synchronized motors.

• Create a printable case or mounting bracket.

• Start testing with real-world mechanical linkages and kinetic art setups.

🎊 This is a huge step forward in making stepper motor control plug-and-play for non-engineers. No code, no libraries — just intuitive hardware and motion.

More to come soon!
