* Exp9_SerialDrive -- RedBot Experiment 9
|
||
|
|
*
|
||
|
|
* The first step to controlling the RedBot remotely is to first drive it
|
||
|
|
* from the Serial Monitor in a tethered setup.
|
||
|
|
*
|
||
|
|
* Hardware setup:
|
||
|
|
* After uploading this sketch, keep the RedBot tethered to your computer with
|
||
|
|
* the USB cable. Open up the Seral Monitor to send commands to the RedBot to
|
||
|
|
* drive.
|
||
|
|
*
|
||
|
|
* This sketch was written by SparkFun Electronics, with lots of help from
|
||
|
|
* the Arduino community. This code is completely free for any use.

|
||
|
|
*
|
||
|
|
* This experiment was inspired by Paul Kassebaum at Mathworks, who made
|
||
|
|
* one of the very first non-SparkFun demo projects and brought it to the
|
||
|
|
* 2013 Open Hardware Summit in Boston. Thanks Paul!
