Program a digital clock in C or embedded C and display it on a 16x2 LED Screen showing HH:MM:SS. Use Atmel Studio 7/6 with dragon board board stk300, Atmega1281, Jtag debugger and a 16x2 powertip lcd screen. The project should have 2 outputs and 2 inputs ideally ie switches to set and change the time. 

If you can don't have the equipment but can run the code in a simulator it's still good as I have it. It just needs to have all the right attributes for it to display on the powertip lcd module.
