How To Make Multifunction LED Chaser With Arduino ||5 in 1||

LED Chaser With Arduino

Hello friends. What's up? Hope doing well. Today we are going to make a simple but very interesting LED Chaser with Arduino.

So let's started............

Required Components:

1. Arduino 

2. LED * 4 Pcs { you can take more }

3. Push Button

4. 100 ohm Resistor [ 1/4 watt ] * 4 Pcs

5. Breadboard

6. Some jumper wires.

7. 10k ohm Resistor 

Circuit Diagram:

Here is the circuit diagram.......

Code:

int buttonstate = 0;
int led1 = 3;
int led2 = 5;
int led3 = 6;
int led4 = 9;
int button = 8;
int brightness = 0;

void setup()
{
  pinMode(button, INPUT);
  pinMode(led1, OUTPUT);
  pinMode(led2, OUTPUT);
  pinMode(led3, OUTPUT);
  pinMode(led4, OUTPUT);
  
  Serial.begin(9600); 
  
}

void mode1(){
  digitalWrite(led1,HIGH);
  digitalWrite(led2,HIGH);
  digitalWrite(led3,HIGH);
  digitalWrite(led4,HIGH);
  delay(100);
  digitalWrite(led1,LOW);
  digitalWrite(led2,LOW);
  digitalWrite(led3,LOW);
  digitalWrite(led4,LOW);
  delay(100);
  }
  
void mode2(){
  digitalWrite(led1,HIGH);
  delay(100);
  digitalWrite(led2,HIGH);
  delay(100);
  digitalWrite(led3,HIGH);
  delay(100);
  digitalWrite(led4,HIGH);
  delay(100);
  digitalWrite(led1,LOW);
  delay(100);
  digitalWrite(led2,LOW);
  delay(100);
  digitalWrite(led3,LOW);
  delay(100);
  digitalWrite(led4,LOW);
  delay(100);
  }

void mode3(){
  digitalWrite(led4,HIGH);
  delay(100);
  digitalWrite(led3,HIGH);
  delay(100);
  digitalWrite(led2,HIGH);
  delay(100);
  digitalWrite(led1,HIGH);
  delay(100);
  digitalWrite(led4,LOW);
  delay(100);
  digitalWrite(led3,LOW);
  delay(100);
  digitalWrite(led2,LOW);
  delay(100);
  digitalWrite(led1,LOW);
  delay(100);
  }

void mode4(){
 
  for (brightness = 0; brightness <= 255; brightness += 5) {
    analogWrite(led1, brightness);
    analogWrite(led2, brightness);
    analogWrite(led3, brightness);
    analogWrite(led4, brightness);
    delay(30); // Wait for 30 millisecond(s)
  }
  for (brightness = 255; brightness >= 0; brightness -= 5) {
    analogWrite(led1, brightness);
    analogWrite(led2, brightness);
    analogWrite(led3, brightness);
    analogWrite(led4, brightness);
    delay(30); // Wait for 30 millisecond(s)
  }

  digitalWrite(led4,HIGH);
  delay(100);
  digitalWrite(led3,HIGH);
  delay(100);
  digitalWrite(led2,HIGH);
  delay(100);
  digitalWrite(led1,HIGH);
  delay(100);
  digitalWrite(led4,LOW);
  delay(100);
  digitalWrite(led3,LOW);
  delay(100);
  digitalWrite(led2,LOW);
  delay(100);
  digitalWrite(led1,LOW);
  delay(100);
  }

 void mode5(){
  mode1();
  mode2();
  mode3();
  mode4();
  }  

void loop()
{
  int value = digitalRead(button);
 
  if(value == 1){
    delay(1000);
  buttonstate = buttonstate + 1 ;
  }
  Serial.println(buttonstate);
  if(buttonstate > 5){
     buttonstate = 0;
  }
  
  if(buttonstate == 1){
     mode1();
  }

  if(buttonstate == 2){
     mode2();
  }

  if(buttonstate == 3){
     mode3();
  }
  if(buttonstate == 4){
     mode4();
  }
  if(buttonstate == 5){
  
  mode5();
  }  


}

Hurray...Our chaser is ready.

This has 5 different function. Pressing the button you can change the chasing style.

 Enjoy : )
