DIY Sunrise Alarm Clock



There is nothing that is more annoying than the beep of an alarm clock. So I designed a simple DIY "sunrise alarm clock" This uses light to wake you up. At the set time, an LED lamp gradually turns on over several minutes. This is less of a shock than the sudden blare of a typical alarm.

    So, I've been having trouble with this project. I set it up as the schematic indicated (you can see my breadboard layout here http://123d.circuits.io/circuits/527082-sunrise-alarm/edit#breadboard) and, while the LEDs come on, they don't brighten. They are quite dim. When you turn the potentimeter, they don't get brighter, but if you turn it all the way to the left, they will dim and then turn off right at the very end of the travel. Not sure what I'm doing wrong here, but it's driving me nuts! Any suggestions would be very greatly appreciated!

    Best,
    Aaron
