Measuring Distance Using UltraSonic Sensor with Arduino

Measuring Distance

    Using Arduino, UltraSonic Sensor & OLED Display

            In this Arduino Tutorial , I will show you How to Measure a Distance of an Object Using Arduino , UltraSonic Sensor & OLED Display . You can watch this Video or Read the following Blogs for More Details.

Working Principle :

            The Major Component Used in this Project was UltraSonic Sensor. UltraSonic Sensor emits a High-Frequency Sound Pulse and Calculates the Distance depending upon the time taken by the echo signal to travel back after reflecting from the Target. 

Components Required :

• Arduino Uno Board
• UltraSonic Sensor
• OLED Display
• Breadboard 
• JumperWires

Construction:

• By using Breadboard, mount UltraSonic Sensor and OLED Display on it . 
• Now power both sensor and display using Arduino Uno Board with the help of Jumpers. 
• Now Connect Trigger & Echo pin of UltraSonic Sensor to the 6th & 7th pin of the Arduino Uno Board . 
• Then Connect SCL & SDA of OLED Display to the A6 & A5 pins of the Arduino Uno  Board. 
• Then setup for the Hardware Portion is done. 
• Let's move on to the Software Portion,Open Your Arduino IDE and Select Measuring_distance_using_UltraSonic_Sensor file.
• Download Required Libraries .
•  And Select Board & Port , Click Upload. 
• That's Solve Guys .!
