The Lingehaven in Gorinchem has asked me to make a counter system that can keep track of how many boats pass through the lock.
I've created a system using a Raspberry Pi that captures button input and processes it as a count in a database.
A web interface runs here, which means that a count can also be done manually and the data can be viewed and exported.
