Introduction to LCD with Arduino
Introduction to LCD with Arduino
Components:
• Arduino Uno R3
• 16x2 LCD Display
• Potentiometer (for contrast adjustment)
• Jumper wires
• Breadboard
Introduction:
LCDs are commonly used for displaying information in various electronic projects. They are affordable, easy to use, and provide a simple way to output data. In this lab, we will learn how to interface an LCD with Arduino Uno and display a simple message along with a timer.
Procedure:
• Firstly we open Tinker cad software
• Then we create a new circuit simulation or open an existing one.
• We drag and drop an Arduino Uno and an LCD component from the components panel onto the work plane.
• We wired the components according to the circuit setup described earlier in the procedure.
• Double-click on the Arduino Uno to open its code editor.
• We Copy the provided code and paste it into the code editor.
• We click on the "Start Simulation" button to simulate the circuit.
• Now we observe the behavior of the LCD screen in the simulation window.
Circuit Setup:-
• Firstly we connect the RS pin of the LCD to digital pin 12 on the Arduino.
• Then we connect the Enable pin of the LCD to digital pin 11 on the Arduino.
• Also Connect the D4, D5, D6, and D7 pins of the LCD to digital pins 5, 4, 3, and 2 respectively on the Arduino.
• Then Connect the RW pin of the LCD to GND.
• Now Connect the VSS pin of the LCD to GND.
• We Connect the VCC pin of the LCD to 5V on the Arduino.
• Also we Connect the VO pin of the LCD to the middle pin of the potentiometer. Connect one end of the potentiometer to GND and the other end to 5V.
• At the end we Place a 10K resistor between the ends of the potentiometer.

comment if you need code
Testing:
• We Power up the Arduino Uno.
• Then adjust the potentiometer to set the contrast of the LCD.
• We observe the message "DANISH!" displayed on the first row of the LCD.
• Also observe the timer counting seconds on the second row of the LCD.
