stepper. Notes-032119 a. ppt From stepper. Notes-031719 a. pptx, we had the following from 03/14/19 to 03/18/19: Note to self: Left and Right pictures look correct Note to self: Above photo says D 0 – IN 2 (Orange). But above timing diagram says it should be PINK D 1 – IN 4 (Blue). But above timing diagram says it should be ORANGE D 2 – IN 3 (Yellow) D 3 – IN 1 (Pink). But above timing diagram says it should be BLUE Note to self: Schematic says IN 1 – Pink (But board has this as BLUE) IN 2 – Orange (But board has this as PINK) IN 3 – Yellow (But board has this as YELLOW) IN 4 – Blue (But board has this as ORANGE)

Data sheet shows this: My motor shows this: stepper. Notes-032119 a. ppt O-B-R-Y-P B-P-R-O-Y A website shows this: B-P-Y-O-R Anyways, we said (from 03/14/19 to 03/18/19) that Orange/Pink and Blue/Yellow are pairs. This may be wrong. I checked that all the 28 BYJ-48 steppers I have, have the colored wiring in the sequence shown above e nc e My motors have the same color sequence given in the u eq s breakdown video nt e r fe Dif

It appears to be displayed at 90, 180, 270, and 360 degrees. NB: I also removed the text displays to the LCD during the loop (as this might be slowing things down).

Angle = -45 – 45 = -90 Since negative, then direction is CW Also 90 * 11. 38 = 1024 steps current. Angle = -45 angle – current. Angle = 0 – 45 = -45 Y Since negative, then direction is CW Also 45 * 11. 38 = 512 steps
