I want to build a digital table top countdown clock to display the number of days left until christmas: days only .
On christmas day the clock will display "merry christmas" flashing or not flashing. A reset switch to start a new cycle and adjust time - days in this case. I can build the circuit based on the 555 and the 4000 series counter; I am not familiar with microcontrollers, but you may include the circuits or sources with microcontrollers, arduino. PIC, etc, so I can have a start. Thank you
