* | Arduino Experimentation Kit Example Code | (and then copy the text and paste it into an empty Arduino Sketch) /*. TMP36 Datasheet Code (no need to type everything in just) To open this, first upload the program then click the button which looks like a square with an antennae. One extra note, this circuit uses the Arduino IDE's serial monitor. We'll output the value over a serial connection to display on the screen. Then to display it we'll use one of the IDE's rather powerful features, the debug window. To convert this from the digital value to degrees, we will use some of the Arduino's math abilities. 25 degrees C = 750 mV, 0 degrees C = 500mV).

It outputs 10 millivolts per degree centigrade on the signal pin (to allow measuring temperatures below freezing there is a 500 mV offset eg. It has three pin's, ground, signal and +5 volts, and is easy to use. To do this we'll use a rather complicated IC (integrated circuit) hidden in a package identical to our P2N2222AG transistors.
