Re: InfraRed ramblings

Yeah, these are unipolar steppers, not bipolar.

I'm using the ULN2003 as driver that came with them. I'll be switching to a ULN2803 for my use.

Re: InfraRed ramblings

I bought some of those stepper motors you linked above. Really cheap, small with a gearbox, but be aware they are wired so you cannot use them with a standard stepper driver module. These have five...

For example

ARGH! That's what they're called. :D I knew these existed, I just didn't know their names.

Re: InfraRed ramblings

There will be minimal light leakage. These will be on either side of a disk, as close as I can get them.

I plan on putting black heatshrink over the LEDs as close as I can to the rotating disk.

if there is any ambient light leakage a ir sensor like SEN-19018 would be better than a photo diode, with the bonus of making
led modulation unnecessary too.

if the distance between led and...
