Super high resolution stepper motor driver
skip to 2:00 to see how far away the stepper/laser is. no tricks!
UPDATE: Higher resolution achieved: • Mega high resolution stepper motor driver
Testing steppers motors with Sine wave patterns. I am actually blown away at how small a step these motors can make. this is a 1.8 degree per step stepper motor but with analog control it can be damn near infinite!
I could measure it but suffice to say it borders on ridiculous.
5v@40ma arduino analogwrite
the dot takes 1m 40s to travel 10cm at around 3 meters. the loop in the arduino has delay(1000) between each step.
i'm not real big on math but i'm sure the answer has lots of zero's after it ;)
