This is another digital clock that uses an bi-color LED array to display time. It’s special purpose is to indicate time when child has to go to bed. As it able to do so in two colors red and green, so no need to learn clock – just follow the color. Red means – go to bed, green time to get up.
Hard to say if it’s working this way – children simply don’t love rules 🙂 Anyway this is great project that is based on multilevel board design to make it compact. Clock is run by PIC18F4550 microcontroller.
