Title: Project 10 off book Zoetrope
Post by: Wimkie07 on May 13, 2014, 02:37 pm
I have made the programming like in the book but I get an error

void loop() {
  onOffSwitchState = digitalRead(onOffSwitchStateSwitchPin);
  delay(1);
  directionSwitchState = digitalRead(directionSwitchPin);
  motorSpeed = analogRead(potPin)/4;


  if(onOffSwitchState ! = previousOnOffSwitchState) {  // error: expected ')' before '!" token
this is the error place   

if(onOffSwitchState == HIGH) {
      motorEnabled = !motorEnabled;

I have programmed it like in the book, so I think I make a mistake but I don't know what the mistake is.

Thank you for helping me.

I found the problem.

It's not ! =
but !=
