hello.. i've been studying electronics and basic digital circuits for a few weeks.. and i wanted to give something a try... i opened up my alarm clock.. and it is programmed by push buttons (obviously).. i would like to hook it up to the parallel port, so i could program to the alarm time from my computer. where would i start with this? is it something basic like... everytime you push a buttom it completes the circuit to send a +5 (1) or what?
