Arduino doesn't turn off vibration after inputting 0

Question

I have arduino UNO with bluetooth module and vibration motor attached. I can turn on the vibrator but cant seem to turn it off. Here's the code

#include<SoftwareSerial.h>//import the serial library

int vib=8;
SoftwareSerial Genotronex(10,11);//RX,TX
int BluetoothData;//the data given

void setup() {
Genotronex.begin(9600);
Genotronex.println("Bluetooth on please press 1 to vibrate");
pinMode(vib,OUTPUT);
// put your setup code here, to run once:
}

void loop() {
if (Genotronex.available()){
BluetoothData=Genotronex.read();{
if(BluetoothData='1'){
  digitalWrite(vib,'1');
  Genotronex.println("Vibrator on");
  delay(500);

  }
  else if (BluetoothData='0'){
  digitalWrite(vib,'0');
  Genotronex.println("Vibrator off");
  delay(500);

  }   
  }
  }
delay(100);
// put your main code here, to run repeatedly:
}

In the bluetooth terminal, it stated <1> Vibrator on when i input '1' but also stated <0) Vibrator on when i input '0' when it should've been Vibrator off.

Appreciate all the help

Answer 1

if(BluetoothData='1'){
                ^

Single = is assignment. Use == for comparisons.

Also, BluetoothData should probably be defined as a local variable in loop() . It'll work either way, but will compile to slightly more efficient (and more readable!) code.
