Let's see your version of using the if/else statement, I've had my little go.
My code from yesterday looks like the below: two leds and a switch, as shown in the attached schematic.
//read a switch and if it's high,
// put a led on. If it's low,
// put a different led on instead.
//LEDs are on pins 5 and 6, with the anodes
// to 5V and cathodes to the pins. So, the
// leds come on when their i/o pins are low
//The switch is on pin 10 with pullup enabled,
// so pin 10 is usually high but goes low
// when the switch is pushed.
//Serial is enabled and the value of the pin
// is shown in the monitor each time thru loop()
byte ledOne=5; // a byte is the smallest type that can store a number
byte ledTwo=6;
byte mySwitch = 10;
bool mySwitchVal; // it can only be on or off so bool is cool
void setup() {
Serial.begin(9600);
pinMode(ledOne, OUTPUT);
pinMode(ledTwo, OUTPUT);
pinMode(mySwitch, INPUT_PULLUP);
}
void loop() {
mySwitchVal= digitalRead(mySwitch);
Serial.println(mySwitchVal);
if (mySwitchVal == 1) // note the == not just a =
{
digitalWrite(ledOne, HIGH);
digitalWrite(ledTwo, LOW);
}
else // if not 1, it must be 0
{
digitalWrite(ledOne, LOW);
digitalWrite(ledTwo, HIGH);
}
}
