Hello,
I was playing with the POT command and couldn't get it to work. I noticed that RCTime looked very similar so I tried it and with a little tweeking it works great! It doesn't work like I assumed it would, but it works. The book shows this:

'RCTIME Pin,State,Var

Low PORTB.3 ' Discharge cap to start
Pause 10 ' Discharge for 10ms
RCTIME PORTB.3,0,W0 ' Read potentiometer on Pin3

I assumed that the "State" value could be 0 or 1, but if I used this:

High PORTB.3 ' Discharge cap to start
Pause 10 ' Discharge for 10ms
RCTIME PORTB.3,1,W0 ' Read potentiometer on Pin3

Then it returned a 1 or 0 depending with the POT at min and max positions.

I can't remember exactly (late night), but I think this is what I ended up with:

High PORTB.3 ' Discharge cap to start
Pause 10 ' Discharge for 10ms
RCTIME PORTB.3,0,W0 ' Read potentiometer on Pin3

This is probably basic, but I didn't know that having the CAP connected to +5V and the POT connected to GND used more power than having the CAP to GND and the POT to +5V. It doesn't seem to use any more power this way than it did without the CAP and POT.
