Re: Running 28BYJ-48 stepper motor in full step mode

Actually, the pattern sequence 1010, 0110, 0101, 1001 did not work. What I discovered is that the pattern 1000, 0100, 0010, 0001 does work. The problem is speed. At 1 millisecond between phases, I appear to be at the limit of the stepper motor speed when using half step mode. When I use full step mo...

Running 28BYJ-48 stepper motor in full step mode

I have a 28BYJ-48 stepper motor with a ULN2003 driver that I have successfully operated in half-step mode, which is pretty much what everyone seems to be using. I want to sacrifice resolution for speed and operate in full step mode, but I haven't been able to get it to work. In half-step mode with l...
