A blog for notes and updates to the book “Making Things Talk”
{ Category Archives }
For people who’ve had trouble getting TextFinder to work with Arduino 1.0-rc1, Michael Margolis has released a new version of the library that should compile for both the older Arduino 0022 and the newer Arduino 1.0-rc1. You can find it on the Arduino playground.
The following examples are affected by this:
Chapter 4
Chapter 6
Chapter 9
Chapter 10
The code in my gitHub repository for these examples is up to date for Arduino 1.0-rc1.
If you’re trying to use any of the Ethernet examples or the Wifi example straight from the 2nd edition of Making Things Talk, you’re probably getting some errors related to the definition of Client and Server. Here’s how to fix them.

/* Lantronix serial-to-ethernet HTTP request tester Language: Processing This program sends serial messages to a Lantronix serial-to-ethernet device to get it to connect to a remote webserver and make an HTTP request. To use this program, connect your PC to the Lantronix module’s serial port as you did when you were configuring the Lantronix module earlier. */
/* Test Server Program Language: Processing Creates a server that listens for clients and prints what they say. It also sends the last client anything that's typed on the keyboard. */
