This question comes from Bill Byrd: LCDs, Servos, and Twitter4J Using Servos with Arduino Servos the Hard Way: Part Three Question “The problem is that my servo doesn’t respond in any way to the potentiometer. I know the servo wiring is fine because it responds to the manual inputs. I know the pot is fine…

This question comes form Richard Reid: Question: “Any idea how I can convert the reading from the temp sensor into Fahrenheit temperatures? The sensor returns a value of “185”…..  that is 185 what?  I very much doubt it is 185 degrees Celsius….  which would mean it’s 365 degrees Fahrenheit here in my bedroom.” Your Challenge:…
