PROJECT – LED MATRIX
In this tutorial you will learn how to use LCD with Arduino and display some text on the LCD.
STEP – 1 Components
Components Required:-
1. Arduino Uno
2. Breadboard
3. LED MATRIX
4. Wires.
STEP – 2: Circuit
The connections are
pretty easy, see the image above with the breadboard circuit schematic.
STEP – 3: Add Library
Before
you can use the LED Matrix on the Arduino, you’ll need to
install the library. It’s easy to install, open up the Arduino IDE. Then go to
Sketch>Include Library>Manage Libraries>search LEDCONTROL>install
LEDCONTROL library.
STEP – 4 : Code
#include "LedControl.h"
#include "binary.h"
/*
DIN connects to pin 12
CLK connects to pin 11
CS connects to pin 10
*/
LedControl lc=LedControl(12,11,10,1);
// delay time between faces
unsigned long delaytime=1000;
// happy face
byte
hf[8]={B00111100,B01000010,B10100101,B10000001,B10100101,B10011001,B01000010,B00111100};
// neutral face
byte nf[8]={B00111100,B01000010,B10100101,B10000001,B10111101,B10000001,B01000010,B00111100};
// sad face
byte sf[8]=
{B00111100,B01000010,B10100101,B10000001,B10011001,B10100101,B01000010,B00111100};
void setup() {
lc.shutdown(0,false);
// Set brightness to a medium value
lc.setIntensity(0,8);
// Clear the display
lc.clearDisplay(0);
}
void loop(){
// Display sad face
lc.setRow(0,0,sf[0]);
lc.setRow(0,1,sf[1]);
lc.setRow(0,2,sf[2]);
lc.setRow(0,3,sf[3]);
lc.setRow(0,4,sf[4]);
lc.setRow(0,5,sf[5]);
lc.setRow(0,6,sf[6]);
lc.setRow(0,7,sf[7]);
delay(5000);
// Display neutral face
lc.setRow(0,0,nf[0]);
lc.setRow(0,1,nf[1]);
lc.setRow(0,2,nf[2]);
lc.setRow(0,3,nf[3]);
lc.setRow(0,4,nf[4]);
lc.setRow(0,5,nf[5]);
lc.setRow(0,6,nf[6]);
lc.setRow(0,7,nf[7]);
delay(delaytime);
// Display happy face
lc.setRow(0,0,hf[0]);
lc.setRow(0,1,hf[1]);
lc.setRow(0,2,hf[2]);
lc.setRow(0,3,hf[3]);
lc.setRow(0,4,hf[4]);
lc.setRow(0,5,hf[5]);
lc.setRow(0,6,hf[6]);
lc.setRow(0,7,hf[7]);
delay(delaytime);
}
/* Copy above Code and Paste in Your Arduino Sketch */
Step 5: Well Done!
You have successfully completed one more Arduino Project and you learned how to use a LED MATRIX Display with Arduino.
THANKYOU!
