Lesson goal: Read the temperature of and plot it in real time


As seen in the last lesson, you saw how to read voltages in from the Arduino, which were generated from the LM35DZ temperature probe. Let's do the same in this lesson, but let's make a real-time graph of the temperature as it comes in.

As you run this lesson, try to change the temperature (with ice, your warm breath, a match, pinch in your fingers, etc.) and watch the plot go up and down in response. Pretty cool huh?

Now you try. Go for it! Fix the analogread argument, and be sure that tempF gets computed as the temperature in $^\circ F$.
