I need to switch on/off a 12V load, high-side, from a PIC running on 5V, and
tried this circuit, but the output is always on.  With the PIC I/O floating
(set as input), the load should be switched off, and with the I/O low, the
load should be switched on.  I'm using 1k for R1 and 10K for R2.  The load
will be up to ~250mA, btw.

Any idea what I'm doing wrong here?  The circuit...
