Hands-On Embedded Programming with C++17

Future developments

There are still many additions that can be made to this system. From the number of sensors that could be supported, further GPIO expander chips, air-conditioning system configurations, room occupancy detection linked into a calendar backend, to clearing out scheduled meetings at an office where nobody showed up, and so on.

There is also the option of switching from ESP8266 as the MCU to a different one, such as ARM-based MCUs, to get wired Ethernet options, along with better debug and development tools. As convenient as it is to have an MCU with Wi-Fi, which one can just stick anywhere and theoretically have it work, the development tools for the ESP8266 aren't that great, and the lack of wired communication options (without ...
