Definitions on dropbot plug ins


Hey I was wondering if someone could define what exactly the shorts test does, and how it does it. Likewise, the dropbot test? Thanks.



The code for all of the hardware tests is available on github.

Specifically, here’s the code for short detection. Basically, it applies a 3.3V source to each channel through a 51kOhm resistor and measures the voltage across the resistor. If a switch is shorted to ground, the voltage will be 0; otherwise, it should be ~3.3V.
