How to Use LCD Keypad Shield for Arduino
In this tutorial, we will learn on how to use the LCD Keypad Shield for Arduino. This shield is compatible for Arduino Uno and Arduino Mega.
Pin assignments:
From this pin assignments, we can conclude that the following pins are free and available to be use for other purposes.
Digital pins: 0, 1, 2, 3, 11, 12, and 13.
Analog pins: A1 to A5.
Video Demonstration:
Source Code:
#include "LiquidCrystal.h"
LiquidCrystal lcd( 8, 9, 4, 5, 6, 7);
void setup() {
lcd.begin(16, 2);
lcd.setCursor(0,0);
lcd.print(" TechToTinker ");
lcd.setCursor(0,1);
lcd.print("Press Key:");
}
void loop() {
int x;
x = analogRead (0);
lcd.setCursor(10,1);
if (x < 60) {
lcd.print ("Right ");
}
else if (x < 200) {
lcd.print ("Up ");
}
else if (x < 400){
lcd.print ("Down ");
}
else if (x < 600){
lcd.print ("Left ");
}
else if (x < 800){
lcd.print ("Select");
}
