Arduino DHT11 + I2C LCD Live Humidity & Temperature Display
In this tutorial, we build a simple Arduino project using the DHT11 sensor and an I2C LCD to display live humidity and temperature readings. Perfect for beginners, this project shows how to wire the components, write the code, and test the sensor in real time.
🔧 Components:
Arduino Uno
DHT11 sensor
I2C 16x2 LCD
Jumper wires & breadboard
📜 Code explained step by step:
Include libraries
Initialize sensor & LCD
Read humidity and temperature
Display values on LCD
💡 Demo: Watch the LCD update as we test with warm air and changes in humidity.
