I'll see what I can manage. Do you have a datasheet for the latch
release scheme you're using?

i don't understand. you just flip the pin high for a few seconds like it does
in the code and it unlatches the door.

I see. That's what I would have assumed, except you said "all it does is trigger
the latch release solenoid, but it's still using this super-fancy motor control shield,"

which made it sound like the latch release solenoid was complicated enough that
it needed to be driven by a fancy motor shield.

basically i will be controlling about 6 pins to drive that motor, and
monitoring 2 pins which will tell me quadrature of its position for that
purpose. and another output pin will control the latch.

this is a diagram of a similar motor, except it shows three hall-effect sensors
and i think our motor might only have two, is that possible? I need to look.

This sounds like fun, and I'm interested in helping with it, including working on
firmware for it.

all you need to do is get the RFID code that Henner wrote to compile in
arduino, and i can do the rest. what do you think of that?

This sounds like you're leaving me the boring part. I think it's silly to port it to
arduino and I am not interested in working on this in the way you've described.

How about we agree on a pinout for the 168P and I write the firmware while you
work out the motor hardware, since you've already started on it?

Then we can get together at a later date, perhaps this coming Tuesday, and

see what we've got. We can reapportion labor as necessary.

Not sure why this private thread ended up on sudo-discuss, btw.
