5. 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.

6. 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;

7. 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;
