Answer 1

You can try:

int Pin22 = 22;
int valuePin22 = 0;

void setup() {

    pinMode(Pin22, OUTPUT);
    digitalWrite(Pin22, LOW);

}

void loop() {

    digitalWrite(Pin22, HIGH)
    valuePin22 = 1;
    Serial.println(valuePin22);
    delay(100);

    digitalWrite(Pin22, LOW)
    valuePin22 = 0;
    Serial.println(valuePin22);
    delay(1000)

}
