The Arduino system offers an easy and open-source method for programming microcontrollers. Normally this means using a serial cable or USB cable attached directly to the microcontroller project. But what if your project is floating in a weather balloon, glued to the bottom of a swimming pool or baked into a loaf of bread? It would be great to upload code changes wirelessly, and even greater if you could do it from several kilometers away.The following example demonstrates how to build a complete wireless solution for uploading code to a remote Arduino microcontroller using a couple of XBee radios, and a handy function for accomplishing wireless resets.
