All, today i gonna to share how Arduino connected to LCD(16x02). LCD 16x02 means 16 character in 2 rows. Connection between LCD and UNO Code: #include <LiquidCrystal.h> int Contrast=75;  LiquidCrystal lcd(12, 11, 5, 4, 3, 2);   void setup()  {     analogWrite(6,Contrast);      lcd.begin(16, 2);   }      void loop()  {      lcd.setCursor(0, 0);      lcd.print("ITS WORK");        lcd.setCursor(0, 1);      lcd.print("WELL DONE");  }

Today, I will share the project where we use 2x Arduino where each Arduino act as Transmitter to measure a distance using Ultrasonic sensor and Receiver controlling L98N motor driver. Ultrasonic Sesnor L298N Motor Driver            Two output Motor Driver with Enable pin for both Motor. Requirement: 1. 2x Arduino 2. 2x MCP2515 CAN module 3. L298N Motor Driver 4. Ultrasonic Sensor 5. 12V battery 6. Download NewPing, SPI and mcp2515 into Arduino. Instruction: 1. Connect Arduino Nano to Ultrasonic sensor. 2. Connect Arduino Nano to MCP2515(1) through SPI connection. 3. Connect MCP2515(1) with MCP2515(2) using CAN-H and CAN-L wire. 4. Connect MCP2515(2) to Arduino Uno through SPI connection. 5. Connect Arduino Uno with Motor L298N. Code: Transmitter: #include <NewPing.h> #include <SPI.h>          //Library for using SPI Communication ...

Yeah, Ultrasonic sensor now its working. Today i am gonna to share the code of how its work:) It quite easy. We just need to connect 4-pin which is VCC,GND,ECHO and TRG from Ultrasonic sensor to Arduino. Done:) Code : int trigger_pin = 4; int echo_pin = 2; int LED_pin = 13; int time; int distance; void setup ( ) {         Serial.begin (9600);         pinMode (trigger_pin, OUTPUT);         pinMode (echo_pin, INPUT);         pinMode (LED_pin, OUTPUT); } void loop ( ) {     digitalWrite (trigger_pin, HIGH);     delayMicroseconds (10);     digitalWrite (trigger_pin, LOW);     time = pulseIn (echo_pin, HIGH);     distance = (time * 0.034) / 2;   if (distance <= 10)         {  ...

Deep interesting in CAN BUS and working in this area encourage me to make a project using CAN BUS as a medium connection between two MCU. Today, i am gonna to share DHT11 temp sensor as a transmitter and give a output to serial monitor as Receiver using MCP2515. Interesting right?:) Code: Transmitter : #include <SPI.h>           //Library for using SPI Communication #include <mcp2515.h>        //Library for using CAN Communication #include <DHT.h>           //Library for using DHT sensor #define DHTPIN A0         //Define DHT 11 Pin Connected to Arduino #define DHTTYPE DHT11 //DEFINE DHTTYPE struct can_frame canMsg; MCP2515 mcp2515(10);       // Set the pin number where SPI CS is connected (10 by default) DHT dht(DHTPIN, DHTTYPE);      //initilize...

A lot of things as newbie to do with Arduino. Today,  we will do a simple circuit using Arduino. Let try.. Code : // set pin numbers: const int buttonPin = 3;     // the number of the push button pin const int ledPin =  11;      // the number of the LED pin // variables will change: int buttonState = 0;         // variable for reading the push button status void setup() {   // initialize the LED pin as an output:   pinMode(ledPin, OUTPUT);   // initialize the pushbutton pin as an input:   pinMode(buttonPin, INPUT); } void loop(){   // read the state of the pushbutton value:   buttonState = digitalRead(buttonPin);   // check if the pushbutton is pressed.   // if it is, the buttonState is HIGH:   if (buttonState == HIGH) {     // turn LED on:     digitalWrite(ledPin,...

Newbie project with Arduino.. Code: #define OUR_LED 12 // the setup function runs once when you press reset or power the board void setup() {   // initialize digital pin LED_BUILTIN as an output.   pinMode(OUR_LED, OUTPUT); } // the loop function runs over and over again forever void loop() {   digitalWrite(OUR_LED, HIGH);    // turn the LED on (HIGH is the voltage level)   delay(1000);                        // wait for a second   digitalWrite(OUR_LED, LOW);     // turn the LED off by making the voltage LOW   delay(1000);                        // wait for a second }
