After a month of my temperature sensor, for our dock, being down, I finally rebuilt it. New board and new circuit. After a couple of hours of debugging, I couldn't get the sensor to work. Replaces the sensor, traced for shorts, and still no go. Finally, I looked at a resistor under normal light. Apparently, the third stripe on the resistor appeared red instead of the orange it was. As many of you probably would have pointed out to me, 47k ohm is very different than the 4.7k ohm it should have been. Dolt! Time to replace my 20 year old fluorescent bench lamp with something with truer colors!
