please I need your help on a particular code that has ultrasonic sensor features in it but its not working to to expected performance.....please can I get your whatsapp number?

brisstone:
Please who have an idea where I can learn Arduino programming in Ilorin, Kwara state.?

int pin = 5;

void setup() {
  // initialize GPIO 5 as an output.
  pinMode(pin, OUTPUT);
}

// the loop function runs over and over again forever
void loop() { 
  digitalWrite(pin, HIGH);   // turn the LED on (HIGH is the voltage level)
   delay(1000);               // wait for a second
  digitalWrite(pin, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);               // wait for a second
}

Do one with omron d6t interfacing with processing software
