I was astonished to find that when the RCX is just on (NOT running a task)
with the light sensor, both switches, and both motors connected that the
Battery voltage drops very quickly. 12 mV a second or more. Is this to be
expected.
Is the RCX watch sposed to reset to 00:00 after turning on and off (red
button)?
I've also noticed that when a touch/switch is activated on port 3, a
increase of 2% occurs on the reflection/light sensor on port 2. Is this
leakage?
Thanks for any answer you care to share.
