For some experiments, two-axes may be perfectly fine, and I’m happy to save the $11.)

(I’m also looking at using a two-axis accelerometer that’s much less expensive than the three-axis one I’ve been using – $4 versus $15. The trade-off is a little bit more complicated protocols semantics, but nothing out of control. It only uses two-wires, rather than the four required for SPI, so schematic designs and board layouts become a bit more manageable.

I’m doing this partially because it would be good to know how it works, but also because it’s electrically more compact. I have been using the Arduino and Atmel microcontroller’s generally using the SPI (serial-peripheral interface), but decided to look at the two-wire (a.k.a.
