input voltage conversion
Archiver

I need to convert an input voltage to an acceptable level for one of
the general-purpose I/O pins on a BS2.
If I'm reading the meter correctly, V = 18.40 volts and I = 14.40 mA.
Do I need to step the voltage down before connecting to my BS2? If
so, how would one go about doing this? (According to the BS2 docs, P0-
P15 should not exceed 50 mA sink.)
Thanks in advance,
