If you have a spare Arduino that is looking for a purpose this DIY Home Automation Box might be something interesting to build.Â
“A DIY project that is a home automation box created with what as brains but pcduino and arduino combo. Nice! This home automation box allows the maker to turn on or off the lights in a room or select color of a hacked oil diffuser (the oil diffuser also created by the maker and made compatible to this project), project the indoor or outdoor temperature and humidity ratings from an arduino node by using RF transmission 433Mhz or create the simple handle for alarms. Like any other amateur DIY, this one too leaves plenty of scope for your imagination.”
