Concepts

Arduino UNO R3 :Arduino/Genuino Uno is a microcontroller board. It has 14 digital input/output pins, 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button.

HC-SR04 :The HC-SR04 is an excellent low-cost ultrasonic sensor that works well with Arduino micro-controllers. It will help to find the distance with ultrasonic sound.

The process:• First connect the VCC and GND pins

to the Arduino’s +5V and GND pins

• Next connect the Trigger and Echo pins to two digital pins on the Arduino, perhaps pins 2 and 3 for example.

• Setting the Trigger Pin to HIGH for 10 microseconds will activate a measurement reading and then the pulseIn() function can be called on the Echo Pin to determine the distance

• The length of the incoming pulse is proportional to the distance measured.

pinMode(triggerPin, OUTPUT);pinMode(echoPin, INPUT);

digitalWrite(triggerPin, HIGH);delayMicroseconds(10);

digitalWrite(triggerPin, LOW);int distance = pulseIn(echoPin,

HIGH) / 2;

The process:• This code returns the raw measurement of the

time for the sound to reach the object. Sound travels at approximately 340 meters per second at sea level. Therefore, the length of time it takes sound to travel 1 meter is 1/340 which is 0.0029 seconds. To calculate the length of time for sound to travel 1 centimeter, we divide this by 100 to get 0.000029 seconds, or 29 microseconds.

int distance_cm = distance / 29;

• For accurate readings, it is recommended to leave some time in between measurements, as the sound waves could be echoing around for a while

• a timeout when calling pulseIn() to avoid waiting a long time for a signal that never arrives. If you are only interested in measuring distances up to 100 cm for instance then you could specify a timeout of 5,800 microseconds (100 * 29 * 2)

int distance = pulseIn(echoPin, HIGH,

5800) / 2;
