 Obviously, now, the chip on the conveyor board is *not* a ULN2003A! I naïvely assumed that it was the same, and I was wrong.
 
-My guess is that the unknown chip is an ~~[L6220](/armdroid/info/resources/datasheets/L6220-darlington-switches.pdf), which conveniently contains two inverted and two uninverted outputs, perfect for driving a unipolar stepper motor with two quadrature signals (which are easily generated by two D-flip-flops wired into each other). Unfortunately I'll never know for sure because the heat sink is obscuring the part number.~~ EDIT: It's actually a UCN4204B, which I can find no datasheet online for, so it is still a mystery chip.

 The original interface to the Armdroid I made used a parallel port, which occupied 8 pins of the Arduino and I really couldn't do much else (sensors, etc). I also didn't have any serial-in parallel-out pin expander chips to be able to reduce the pin usage of the Arduino.
 
-Then my engineering teacher taught us about shift registers and how they are made out of flip-flops... and I remembered that I had a spare Armdroid circuit board lying around, which conspicuously uses eight quad D flip flop integrated circuits ([74LS175](/armdroid/info/resources/datasheets/74LS175-d-flip-flop.pdf)) to hold the bits for the stepper motors. Since I didn't need the circuit board, I pulled out two of them (thank God for the IC sockets!) and started wiring them up into a shift register. I also wrote [some Arduino code](https://github.com/dragoncoder047/armdroid/blob/c06672e7eefa750ace01bf089cd30fd8e7fa89f4/code/armdroid-class/armdroid.hpp#L33-L71) to interface it to the homebrew shift register. I haven't completely wired it up yet, but I'm crossing my fingers it will work. In theory it should.
