sir please add pin header
Ok next time
Not working in Samsung phone....when i connect to the fake wifi it doesn't redirects to login page
Sir please DWIN TOUCH DISPLAY all videos share
url please
Software name pls
Why not english ?
Because I make tutorials for Hindi based audience

DWIN display me kaise analog value so kare ga bhai
Okay I will make the tutorial for dwin display where you can show any value to display
Bro this trick not working in my laptop hp ka
how works on raspberry pi 4?
Bhai diagram lcd breadboard ka ache se bhejd o
Nahi Hua Bhai
TNX brother 🎉❤ problem solved
Welcome 👍
Bro where can i get the code
20x4 lcd display code: #include <Wire.h> #include <LiquidCrystal_I2C.h> LiquidCrystal_I2C lcd = LiquidCrystal_I2C(0x27, 20, 4); void setup() { // Initiate the LCD: lcd.init(); lcd.backlight(); Serial.begin(9600); } void loop() { lcd.setCursor(0,0); lcd.print("Hello World "); lcd.setCursor(0,1); lcd.print("Second rows"); }
Arduino i2c address scanner code: #include <Wire.h> void setup() { Wire.begin(); Serial.begin(9600); while (!Serial); Serial.println("-----------------------"); Serial.println("I2C Device Scanner"); Serial.println("-----------------------"); byte error; byte address; int Devices; Serial.println("Scanning..."); delay(1000); Serial.println("--------------------------------"); Devices = 0; for (address = 1; address < 127; address++ ) { Wire.beginTransmission(address); error = Wire.endTransmission(); if (error == 0) { Serial.print("I2C device found at address 0x"); if (address < 16) { Serial.print("0"); } Serial.print(address, HEX); Serial.println(" !"); Devices++; } else if (error == 4) { Serial.print("Unknown error at address 0x"); if (address < 16) Serial.print("0"); Serial.println(address, HEX); } } if (Devices == 0) { Serial.println("No I2C devices found "); } else { Serial.println("-------------- Done!!! -------------"); } } void loop() { }
Hello , mai DWIN display pr se keyboard ke through data send kr rahi hu esp 32 . but dwin se send nhi ho raha data . aur esp32 recv nhi kr pa raha hai . ky aap mujhe bata skte hai main esp32 pr string data kaise recv kr skti hu display ke keyboard se ???
Definitely I will make the video on this topic very soon
can i get the code
Yes sure I will give it: #include <Wire.h> #include <LiquidCrystal_I2C.h> LiquidCrystal_I2C lcd(0x27, 20, 4); // Set the LCD address to 0x27 for a 20 chars and 4 line display const int MQ135_PIN = A0; // Analog pin for MQ135 sensor void setup() { lcd.init(); // Initialize the LCD lcd.backlight(); // Turn on the backlight // Print a welcome message lcd.setCursor(0, 0); lcd.print("MQ135 Sensor Data:"); } void loop() { // Read analog value from MQ135 sensor int sensorValue = analogRead(MQ135_PIN); // Print the sensor value on LCD lcd.setCursor(0, 1); // Set cursor to second row lcd.print("Value: "); lcd.print(sensorValue); // Add more processing or delay if needed delay(1000); // Delay for 1 second before reading again }

@mtechlearner bro is this 900A gsm module support vi 4g SIM? Please reply
It's not support 4g Sim It's support 2g so u can use Airtel Sim but remember don't work this with jio sim
