Specifications:

Step 1: Components Required

To interface an Ultrasonic Sensor with an Arduino and view the distance on the serial monitor you'll need:

Arduino Uno
HC-SR04 Module
BreadBorad
Jumper wires

You'll need a laptop or a PC to upload code to the Arduino and view the Distance on the Serial Monitor.

Step 2: A Little About HC-SR04

The HC-SR04 is an ultrasonic ranging module. This economical sensor provides 2cm to 400cm of non-contact measurement functionality with a ranging accuracy that can reach up to 3mm. Each HC-SR04 module includes an ultrasonic transmitter, a receiver and a control circuit.

There are Four Pins on the HC-SR04. They are :

Vcc (5V supply)
Gnd (Ground)
Trig (Trigger)
Echo (Receive)

The key features to be noted are:

Operating Voltage: 5V DC
Operating Current: 15mA
Measure Angle: 15°
Ranging Distance: 2cm - 4m

Step 3: The Arduino Serial Monitor

The Serial Monitor is a part of the Arduino IDE. It is also available in the Web IDE. It allows you to send and receive data from the board connected via USB. This is using the concept of Serial Communication.

You can send the commands by typing in the window on the top and pressing 'Enter' or clicking 'Send'. The data from the board is displayed below that.

This is very useful when debugging the code, or if you need to give inputs to the board, This is probably the most useful tool in the IDE. The more you use it, the better you get at testing complex projects that takes inputs and provides consequent outputs.

Step 4: The Circuit

The connections are as follows:

Vcc to 5V Pin of the Arduino.
Gnd to Gnd Pin of the Arduino.
Trig to Digital Pin 9 .
Echo to Digital Pin 10.

Refer the schematics for more clarity on the connections.

. Few things to remember while building the circuit

Avoid placing the sensor on metal surfaces to avoid short circuits which might burn the sensor.
It is recommended to put electrical tape on the back side of the sensor.
You can also directly connect the Ultrasonic sensor to the Arduino with jumper wires directly.
