ive got a project for school thats an option but its worth alot of extra credit. in multisim, i need to make a circuit that has a keypad with a 4-digit LCD display, a 0-9 keypad, and a switch. i need the circuit so that i can put in 4 digets in the keypad and they are banked up on the LCD. after pushing a momentary switch, the countdown starts (the lcd should be MM:SS wher m=minutes and s=seconds) after the count down is done, another switch is closed and a light goes on. ac or dc power works. thanks a million if you can do this for me.





thanks again,
Brett
