The book contains a number of software labs, which describing interesting technology that can be programmed in C. The first of these labs is for the Arduino micro-controller. We ask you to create a plant monitoring system which will report when a plant needs watering. If you are working on a Mac, you can make this code a lot cooler, because the Mac has built-in speech synthesis software. If you create a script like this:

#!/bin/bash
while true
do
  read level
  say "$level"
done

and put it in a file called something like speak.sh, you can run it from the Terminal and it will say everything you type in:

$ ./speak.sh
Hello 
Goodbye

If you get your Arduino code to send data to the serial port, and you redirect this data into the speak.sh script, you can get your Arduino to talk!

Have fun. :-)
