Visitor counter circuit using IC 4026 & 7-segment display
Hello Engineers. At places like small gatherings or meeting halls, small conferences, and classrooms its good to employ a visitor counter. This counter will count the visitor number of persons entered in the room or hall. The circuit explained in this tutorial today, is using two CD4026 ICs with two 7-segment LED display. This Digital visitor counter circuit can go up to 99 counts. As soon as a person enters the room, the counter value increments by 1. So, let's start with our topic Digital visitor counter circuit. 7- Segment LED Display A 7-segment display module is an electronic device to display letters, digits, and numbers. These are the modules that are mostly used in devices such as electric meters, voltage stabilizers, test instruments, etc. Instead of the complex dot matrix displays, they are better and easier. They have separate seven segments that help to make a letter or number. Read more.. Demonstration picture on how it works.
