Resources and Going Further
Once you've got serial communication working, you're ready to start playing with serial projects. Consider connecting to a GPS module like the GP-20U7, taking a look at our tutorial on GPS and watching the serial strings roll by. Or, you can use the Serial Basic to program and debug devices like the Arduino Pro Mini. There are tons of devices that use serial to communicate, so go explore!
The Serial Basic programming an Arduino Pro Mini
Heads up! The image shows the Serial Basic connected to an Arduino Pro Mini 3.3V/8MHz. If you are using an Arduino Pro Mini 5V/16MHz, make sure to adjust the jumper pad for the voltage selection on the back of the Serial Basic.
