Introduction: Measure Box (Distance Sensing) Using Ultrasonic Sensor~The Easiest
Step 1: HOW IT WORKS`
HOW IT WORKS?
A special sonic transducer is used for the ultrasonic proximity sensors, which allows for alternate transmission and reception of sound waves. The sonic waves emitted by the transducer are reflected by an object and received back in the transducer. After having emitted the sound waves, the ultrasonic sensor will switch to receive mode. The time elapsed between emitting and receiving is proportional to the distance of the object from the sensor.
Step 2: COMPONENTS
>ULTRASONIC SENSOR HC-SR04
>16*2 LCD SCREEN
>POTENTIO METER(ADJUSTING CONTRAST OF LCD)
Step 3: HEADER PIN
USING HEADER PIN
Use header pin so that You can easely make this project using only MALE TO FEMALE & FEMALE TO FEMALE JUMPER WIRES
Step 1: Place the Header Pin into the pins of Arduino After it glueing it will look like this.
Step 2:Using GlueGun, Glue the header pin to Arduino so that it does'nt become loose.
Double check whether the header pins are not loose,otherwise there will be no output from the pin!!!
Step 4: CIRCUIT
CONNECT ARDUINO ACCORDINGLY!
D7- DIGITAL PIN 2
D6 - 3
D5 - 4
D4 - 5
E - 11
RS - 12
VDD (+) RAIL BREADBOARD
A (+)RAIL BREADBOARD
VSS (-)RAIL BREADBOARD
K (-)RAIL BREADBOARD
RW (-)RAIL BREADBOARD
Step 5: THE BOX
USE A BOX OF MEASURE MORE THAN
13 CM LENGTH
11 CM BREADTH
6 CM HIGHT
USE A BOX OF MORE LENGTH or else everything will be a little messy! (as in the box)
Step 6: MAKE HOLES
MAKE HOLES FOR THE
STICK EVERYTHING USING A DOUBLE SIDE CELLOTAPE
Step 7: KEEP EVRYTHING INSIDE THE BOX!
AS I HAD CHOOSEN A SMALL BOX EVERYTHING SEEMS A LITTLE MESSY!
BE SURE TO TAKE A BIG one!
USE A 9V battrey/Powerbank to power the arduino
TIP : Cover the box with some colour paper / paint it
Step 8: DATASHEET
Step 9: Code
Download the Code from the link and open it with Arduino IDE.
Step 10: Done!
You can see the Current Distance from the object in front on the LCD screen....
You can adjust the contrast (Sometimes the display might be blured)by turning shaft of the Potentiometer!
