This is used to read the output pulses coming from the water flow sensor. When Arduino detects the pulse, it immediately triggers the pulseCounter() function. This function then counts the total ...

Arduino leak sensors only have three pins to connect, making them easy to wire ... Counting your own pulse is a thing of the past with components like a pulse sensor. Arduino pulse sensors have ...

In this particular case, it’s a DIY USB polygraph-like machine by [Juangg] using an Arduino and sensors on the hardware side, and a Python front end for data visualization. It’s even complete ...

GND of the module is the common (0V) connection. The digital signal output to be detected (usually marked as DO in the module) is applied to D2 input of the Arduino. Analog output (marked as AO) from ...
