Is there any way to make a 4 digit (mm:ss) countdown timer w/o using a PIC? I need to countdown 60-90 mins and have a buzzer go off when it reaches 0 and I would be happy for 2 digit (mm) display. I have no experience w/ PICs nor do I have the money to invest in learning at this time. Unfortunately, all of the designs I have seen either use a PIC or they use some type of 555 circuit but w/o a display. Any ideas?
