Address given sensor an electric jack with shield

Hi :slight_smile: , I wanted to know how to record information from the sensor an electric jack.

I must be able to display the values ??of the sensors (pulse) on the arduino IDE console but I do not see how.

Thank you in advance for your help.

Sorry what is it? Can you post a picture?
What do you want to measure, number of times it goes up and down, or how far in or out it is?
