In this chapter, we developed a working prototype of a remote home monitoring system and also learned the process of hardware product development simultaneously. In the project, we utilized most of the hardware components and software tools that we used throughout the book. We began by designing the system architecture so that we could coordinate the utilization of these tools. Later, we ventured into the actual development stages, which included designing the hardware units and developing programs to run these units. In the end, we provided a list of improvements to make this prototype into a real commercial product. You are welcome to use this methodology to develop your future projects and products, as you now have experience working with this one.

In the last chapter, we are going to utilize the same project development methodology to create an interesting project that utilizes your messages from a social network website to give you control over your hardware.
