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...
I was considering laying a limit switch flat along the outer edge of the disk, and use a notch to catch the limit switch roller. But I'm liking the hall sensor even more:
- no...
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.

Since this question has come up again, I thought I'd throw this module out to the masses. It is something I worked on a while back, with DT's help. Amid life's other priorities, it got put on the shelf to collect dust.
The basic idea is that by adding the module as an INCLUDE and inserting a couple of commands inside your code, you can have the PIC send timing data to your PC via the hardware serial port. It's made for 18F PICs (although some 16Fs may work too). You also need a timer that is not being used for anything else.
1) Instructions are included, as well as a small example.
2) It worked well for me, and as I recall, DT in testing.
3) Use it however you want.
4) I won't be able to offer much support, but figure there are enough knowledgeable folks around here that can help those who need it.
NE555 with solenoid
I'd like to activate a solenoid for a brief moment. Does this timer look correct?

- I added a large cap alongside the solenoid; value is just preliminary.
- the opto is to isolate the...
