ELECTRONICS - [counter device]
This project is about a counter: a device to measure the time a certain contact is open. (For example: measure the time a relay is clicked). This time is showed on a few 7-segment displays, in seconds.
The design doesn't include a PCB design, feel free to make one. I decided to use my previously designed counter PCB (picture is shown below). This counter has 4 digits, so I can count up to 9999 seconds (almost 3 hours).
