Arduino Starter Kit Section Guidelines

Great work with Arduino starter kit!
i received it yesterday from RS Components, beautiful package, and much more i'd appreciate the book too, at 60yo as absolute beginner in electronics i'm happy to say i have understood this night more than in previous 60 years :).
Just an info about Project2- Love-o-meter- : the temperature sensor, as referred in the book, is supposed to be a TMP36.
In my "components box" the temp sensor is not a TMP 36, and seems it works badly, may be because it is not a TMP36 ? May be the data in the datasheet are not the same as TMP36?
