Quite a few years ago I built a curtain opener using lego bits and pieces and controlled by a 386PC.
This was upgraded to a RF remote control system using geared DC motors.
Now it's time for version 3.
I plan to reuse the RF remote stuff but hope to drive 2 stepper motors controlled by an 18X and clock chip.
I've attached a preliminary circuit schematic. Comments or suggestions are welcomed.
