Hmm... just figured out I can use Arduino to control some BCD to
7Seg decoder/Drivers..... (like the 7447 / 7448)<br>
<br>
Is it sad that I didn't even have to look those chip numbers up?
Even that the 7447 drives common cathode displays while the 7448
drives common anode....<br>
<br>
I used to spend my allowance at Radio shack as a kid.... I've long
forgotten the pinouts, but I could probably still recall the 7400
NAND gate pinouts if I really tried :-)<br>

Chip has a Si, So, CLK and CS so hopefully that will suffice.

Just noticed that the full 360-degree gauge output has some
interesting serial data input requirements. <br>

I suspect "CS" == Chip Select. :)

Pssst. Hey buddy! Got some neat h-bridges here. One owner!
Only driven on Sundays! :)
