Automated light controller
Inside this recipe, we are going to continue exploring M2M communications with the Arduino MKR1000 board, this time by creating an automated light controller based on Arduino. A first module will be in charge of detecting the ambient light level, and then sending alerts to a second module, which will switch a light on or off, depending on the received alert.
Getting ready
To control a lamp in this project, we are going to use a very convenient component called the PowerSwitch Tail:
These components allow us to easily control devices powered by the mains electricity from an Arduino board, as you can just plug it into the mains ...
