Hi to all i'm new to this site and could do with some help
i need a up/down counter i.e i have a conveayor that takes 3 rolls of bread into an oven then an output to switch on the oven i need to to count each one so it knows 3 have gone in as the convayor moves the bread to the exit i need it to count down then when the last is out the timer to switch off the oven but if i put on 2 bread then the 3rd the 1st one comes out the counter to count up and down so it knows how many at one time is in the oven hope this makes sence to someone out there there would be a maximum of say 6 bread in the oven at any one time

a little project to some i hope
