Introduction: Simple Distance Measuring Device
In this project we are going to learn how to use the HC-SR04 PING))) ultrasonic sensor to measure distance. This sensor is also often used on robots to detect obstacles.
Difficulty level: Easy
Time needed: ±10 minutes
Step 1: Things You'll Need
Step 2: Plug the PING Sensor and LCD
GND (pin 1) to potentiometer (left pin)
VCC (pin 2) to potentiometer (right pin)
VO (pin 3) to potentiometer (center pin)
RS (pin 4) to arduino digital pin 12
RW (pin 5) to potentiometer (left pin)
E (pin 6) to arduino digital pin 11
D4 (pin 11) to arduino digital pin 5
D5 (pin 12) to arduino digital pin 4
D6 (pin 13) to arduino digital pin 3
D7 (pin 14) to arduino digital pin 2
left pin to arduino GND
right pin ro arduino 5V
VCC to arduino 5V
Trig to arduino digital pin 7
Echo to arduino digital pin 6
To arduino DC power socket
Step 3: Upload the Code
Step 4: Have Fun! Show It to Your Friends :)
Yay! you have finished making your own measuring device. Now you can measure things without using a ruler! You can adjust the LCD brightness using the potentiometer. Feel free to give comments or ask questions and stay tune for my next project ; )
nipon4666 made it!
We have a be nice policy.
Please be positive and constructive.
