Arduino code:
#define trigPin1 A1
#define echoPin1 A2
long duration, distance,firstsensor,proximity ;
void setup()
{
pinMode(trigPin1, OUTPUT);
pinMode(echoPin1, INPUT);
pinMode(8, OUTPUT);
pinMode(13, OUTPUT);
}
void loop() {
SonarSensor(trigPin1, echoPin1);
firstsensor = distance;
proximity=firstsensor;
if(proximity
