What started off as a DIY sunrise alarm turned into something even more useful with a completely network/wifi controlled light. The light comes on gradually in the morning over a period of 30 minutes to wake me naturally like a sunrise would. During the day and evening I can turn the light on, off and various levels of brightness all from the web browser on my laptop or phone. I plan to block up the sides of the servo to lower the noise. I’m using a regular household dimmer, a servo motor and a raspberrypi.
