Hello to the Arduino community !
I’m a novice with arduino, and I want to do a project with a hall effect sensor (a water flow sensor ref:YFS 201) and a LCD display 16x2.
I have an Arduino Uno and I figured out that the hall effect sensor use external interrupts and need to be plugged on pin 2.
According to what I found, the LCD display need to be wired with the pin 2: LiquidCrystal lcd(12, 11, 5, 4, 3, 2).
Do you have any idea about what should I do because I have 2 wires for only 1 pin ?
Thank you !!!
