This YouTube video tutorial shows how to interface an LM35 temperature sensor with Arduino Uno, displaying readings on a 16x2 LCD while demonstrating ADC conversion and serial output. Users wire the LCD with RS to pin 13, EN to pin 12, and data pins D4 to D7 to Arduino pins 11 through 8, operating in 4-bit mode for efficiency.
Updated Wiring
LM35: VCC to 5V, OUT to A0, GND to GND.
LCD: RS→13, EN→12, D4→11, D5→10, D6→9, D7→8; VSS→GND, VDD→5V, V0→10k pot wiper for contrast, RW→GND.
Backlight: A→5V via 220Ω resistor, K→GND.
Project Highlights
Standard libraries like LiquidCrystal handle initialization for these pins, reading ADC from LM35 (10mV/°C scale), and printing to both LCD and Serial. This setup frees pins 0-1 for serial debugging and avoids I2C modules. Tutorials confirm compatibility with Arduino Uno in breadboard prototypes.
