Hello everyone, I found this website to be interesting and it appears to me that a lot of solutions are being answered. I want to see if it will work for me. I am designing a project that is entitled Smart Restroom. What I am trying to do on this project as of right now is try to figure out how to use a counting system that will keep a consistant count of people entering the restroom and exiting the restroom and displaying it on the outside of the door so that a person will know if the restroom is over crowded. The goal of the counter is to avoid the over crowdedness of people in public restroom areas. So far I have been instructed to use a BCD Counter (7490N) and I don't know how to reset the display. Could someone please inform me on how I can reset the display? So far it stays at nine.
