Using values from a proximity senor in an IF statement!

[JadeMaveric]

Short Answer

//assuming sensor input pin is at pin4
``
//get input and store it var proximityInput = digitalRead(4); //will be either "HIGH" or "LOW" //check accordingly if ( proximityInput == "HIGH" ) { ....//do something } else if ( proximityInput == "LOW" ) { ....//do something else } else { ....//do something if neither }

Syntax is the same as C++.

edit
The code var proximityInput = digitalRead(4) doesn’t work as expected. (digitalRead() doesn’t return anything)
Adapt it according to the code here

After geting HIGH or LOW input from a vibration detector , how to glow a LED?

var vibration = ''; function setVibration( val ) { ....vibration = val; } function updateLed( sensorPin, ledPin ) { ....//get state for vibration sensor and store it ....digitalReadHandler( sensorPin, setVibration ); ....//vibration now holds either HIGH/LOW ....//accordingly update the led ....digitalWrite( ledPin, vibration ) }
