Many people find the beep of an alarm clock to be a very unpleasant way to wake up. One alternative is to use lights to wake you up. For instance, a “sunrise alarm clock” gradually increases the brightness of a light near your bed at the set time. This helps some people to wake up more gently.
In this project, I am going to show you how to make a simple light alarm circuit. The timing is performed by a cheap outlet timer. Then I add a simple LED circuit that gradually increases the brightness of the LEDs over several minutes. You can then put the lights into any housing that you want and make your own sunrise alarm.
