I´m working in a simple sketch that read a hall sensor from Node MCU with the Arduino IDE but i dont understand very well what happen because i thought there are no mistery...digitalRead(pin) and so . I was trying with different kind of Hall sensor that i have on my studio with no luck. Any tip?...Is my first time working with Esp8266

Thanks in advance!

What type the hall sensor? Sensor output type? If opencollector the output, need the pullup resistor

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
