Have you got it??

Code:: const int pingpin=4; const int led = 13; void setup() { Serial.begin(9600); pinMode(led, OUTPUT); } void loop() { long duration, cm; pinMode(pingpin, OUTPUT); // Clear the trigger digitalWrite(pingpin, LOW); delayMicroseconds(2); // Sets the trigger pin to HIGH state for 10 microseconds digitalWrite(pingpin, HIGH); delayMicroseconds(10); digitalWrite(pingpin, LOW); pinMode(pingpin,INPUT); // measure the ping time in cm duration = pulseIn(pingpin, HIGH); cm = duration * 0.034 / 2; if(cm<100) { digitalWrite(led,HIGH); } else { digitalWrite(led,LOW); } delay(100); // Wait for 100 millisecond(s) }

It seems I have to type it with hands
