This simple test sketch gives me an else without if error, but it's right there before it. If I remove the else code it compiles. Is this a bug?
const int motor1Pin = 3; // H-bridge leg 1 (pin 2, 1A)
const int motor2Pin = 2; // H-bridge leg 2 (pin 7, 2A)
const int ledPin = 13; // LED
const int button1Pin = 8; //Forward button
const int button2Pin = 9; //Reverse button
// variables will change:
int buttonState1 = 0; // variable for reading the pushbutton status
int buttonState2 = 0; // variable for reading the pushbutton status
void setup() {
// set outputs:
pinMode(motor1Pin, OUTPUT);
pinMode(motor2Pin, OUTPUT);
pinMode(ledPin, OUTPUT);
pinMode(button1Pin, INPUT);
pinMode(button2Pin, INPUT);
}
void loop() {
// read the state of the pushbutton1 value:
buttonState1 = digitalRead(button1Pin);
// read the state of the pushbutton1 value:
buttonState2 = digitalRead(button2Pin);
if (buttonState1 == HIGH) // check if a pushbutton is pressed.
{
// turn LED on:
digitalWrite(ledPin, HIGH);
//turn motor on forward
digitalWrite(motor1Pin, LOW); // set leg 1 of the H-bridge low
digitalWrite(motor2Pin, HIGH); // set leg 2 of the H-bridge high
}
else if (buttonState2 == HIGH); // check if a pushbutton is pressed.
{
// turn LED on:
digitalWrite(ledPin, HIGH);
//turn motor on backward
digitalWrite(motor1Pin, HIGH); // set leg 1 of the H-bridge low
digitalWrite(motor2Pin, LOW); // set leg 2 of the H-bridge high
}
else {
// turn LED off
digitalWrite(ledPin, LOW);
//turn motor off
digitalWrite(motor1Pin, LOW);
digitalWrite(motor2Pin, LOW);
}
}
