Please help me i cant seem to find where i did wrong

if (onOffSwitchState != previousOnOffSwitchState){

error: 'previousOnOffSwitchState' was not declared in this scope

const int controlPin1 = 2;
const int controlPin2 = 3;
const int enablePin = 9;
const int directionSwitchPin = 4;
const int onOffSwitchStateSwitchPin = 5;
const int potPin = A0;

int onOffSwitchState = 0;
int previousOnOffSwithState = 0;
int directionSwitchState = 0;
int previousDirectionSwithState = 0;

int motorEnabled = 0;
int motorSpeed = 0;
int motorDirection = 1;

void setup(){
  pinMode(directionSwitchPin, INPUT);
  pinMode(onOffSwitchStateSwitchPin, INPUT);
  pinMode(controlPin1, OUTPUT);
  pinMode(controlPin2, OUTPUT);
  pinMode(enablePin, OUTPUT);
  
  digitalWrite(enablePin, LOW);
}
void loop(){
  onOffSwitchState =
    digitalRead(onOffSwitchStateSwitchPin);
  delay(1);
  directionSwitchState =
    digitalRead(directionSwitchPin);
  motorSpeed = analogRead(potPin)/4;
  
if (onOffSwitchState != previousOnOffSwitchState){
    if(onOffSwitchState == HIGH){
      motorEnabled = !motorEnabled;
    }
  }
  
  if (directionSwitchState !=
  previousDirectionSwitchState) {
    if directionSwitchState == HIGH) {
      motorDirection = !motorDirection;
    }
  }
  
  if (motorDirection ==1) {
    digitalWrite(controlPin1, HIGH);
    digitalWrite(controlPin2, LOW);
  }
  
  else {
    digitalWrite(controlPin1, LOW);
    digitalWrite(controlPin2, HIGH);
  }
  
  if (motorEnabled == 1) {
    analogWrite(enablePin, motorSpeed);
  }
  else {
    analogWrite(enablePin, 0);
  }
  previousDirectionSwitchState =
    directionSwitchState;
  previousOnOffSwitchState = onOffSwitchState;
}

you wrote "int int previousDirectionSwithState = 0;" instead of "int previousDirectionSwitchState = 0;" spelling issue... 8) c is missing

Hi, can you tell us

  1. What your sketch is trying to do?
  2. What it is doing?
  3. Post the complete sketch.
  4. Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png or pdf?

Seeing this as your first line did not help.

@Wicced, i think there's a couple of spelling mistakes you did especially the Switch part cause on 2 places you have Swith. it's supposed to be Switch with a c. :sunglasses:
