Measuring_distance_using_HC-sro4

 Material required-:

  1. Arduino Uno
  2. Jumpers
  3. HC-SRO4 (Ultrasonic sensor)

This is a project in which u can make a distance measurement circuit using HC-SRO4 Ultrasonic sensor you simply have to connect the sensor with Arduino Uno board . You can view the output on serial monitor , make sure that you have selected the correct baud  otherwise it will not work .I hope you all will enjoy this .If you want me to make a post on your idea or project just let me know in the comment section .  

  • VCC pin    to    5volt(5v).(Arduino board)
  • TRIG pin      to        digital pin 4(Arduino board)
  • ECHO pin     to        digital pin 5(Arduino board)
  • GND pin     to    GND pin (Arduino board)




ARDUINO CODE


const int trigPin=4;
const int echoPin=5;
long duration;
long distance;
void setup() {
Serial.begin(9600); 
pinMode(trigPin,OUTPUT);
pinMode(echoPin,INPUT);
 
 }
void loop() {
 //trigerpin
 digitalWrite(trigPin, LOW);
 delayMicroseconds(2);
 digitalWrite(trigPin, HIGH);
 delayMicroseconds(10);
digitalWrite(trigPin, LOW);
 duration = pulseIn(echoPin, HIGH);
 distance = duration*0.034/2;
 
Serial.print("Distance in cm :   ");
Serial.println(distance);
}

Automatic Water Pumping System

Image
Here's a "Automatic Water pumping system" which controls the  water pump motor. The motor gets automatically switched on when water in tank falls below the lower limit . Similarly, its get switched off when the water is filled up( upper level ). This circuit is built with the help of 555 Timer IC Which is best and cheap.    Material required-: PCB Board 555 Timer IC 1k ohm Resistor x 2 220 ohm Resistor x 2 2 Pin Screw Terminal 5V Relay Battery(9v) Transistor (BC 547) Diode (IN4007) Led  Automatic Water pump Circuit-: If you guys have seen my previous post of relay module you must somewhat familiar with upper part of the circuit ,in which we just have to trigger the base pin of transistor to turn the relay on .Just like that, Here we are using output pin (3) of 555 IC to trig the base pin .   When the water level goes up and touch the pin 6 of 555 IC ,output of Pin 3 goes low(0) which switches off the motor. When the level goes below the low level ,that is pin 2 ...

Wireless Communication Between Two Arduino Board Using HC-05 Module

Image
In this post I will show you how you can communicate between two Arduino Boards using HC-05 Module. I am using Arduino IDE's version 1.8.7.  There are now newer modules that use a 3.0-20170601 firmware due to which module gives an error, But I will show you how you can fix this error. Just follow the exact same steps listed below and you will not get any error. Material Required-: PCB Board Arduino Uno x 2 Led Bluetooth Module(HC-05) x 2 Push Button (Switch) Resistor (1k ohm) Jumper Wire Connection for AT Mode -: 5V to Arduino 5V GND to Arduino GND TX to Arduino TX(D1) RX to Arduino RX(D0) Enable Pin to 5V Connections for AT Command Mode Step-1: Upload Blank code on Arduino Board. Step-2: While connecting supply to module long press the "Key Button" situated above enable pin. Now, You will see a delay in flashing of HC-05 led, that's means you are successfully entered in AT Command Mode. Step-3: Now open serial monitor . Remember that HC-05 requires Both "NL and ...

Interfacing "Bluetooth Module" with Arduino Uno

Image
  Materials required-: Arduino Uno Board Bluetooth Module (JDY-30) Breadboard Led (as per your choice) jumpers Resistors (220 ohm )  Hey guys, This is our 10th project using "Arduino Uno" in this project I'm gonna show you how you can connect to a Bluetooth module and operate led . This is the similar concept used in "Home Automation" projects in upcoming posts I will show you how you can make your own Home automation system. If you guys have any doubts you can contact me through email or contact us form in menu. If you want  me to make a project based on  your ideas just let me know in the comment section. HAPPY LEARNING!
