I want to build a counter to track completed cartridges with an optical sensor. I found a kit for the counter that will count up every time the ground and positive are connected. I have a two wire optical sensor that would continuously connect the ground and power except when a cartridge breaks the light. I need a circuit that would use the sensor, but only bridge the outputs when the sensor is triggered.
These are the parts I found:

I am open to other solutions
