Hello and a very good day. I am currently doing my final year project which involving Arduino KY-031 Knock Sensor as my input signal and it is apparently a digital type of sensor. So, my question is can the digital signal be converted to analog signal ?
The reason I need it to be analog signal because I wanted it to be classified into 3 type of stages (low,medium,high).
p/s: I am using Arduino Uno as my controller.
