Elaborate 2: Scattering Pattern with LEDs
Objective:
Blink Five LED in scattering Pattern
Schematics:
Connections:
Reference Picture:
Ardublock
Click on Ardublock to open the Ardublock window and put the following blocks together.
Arduino Code
void setup(){
pinMode(2,OUTPUT); //Set pins D2 to D6 as outputs
pinMode(3,OUTPUT);
pinMode(4,OUTPUT);
pinMode(5,OUTPUT);
pinMode(6,OUTPUT);
}
void loop(){
digitalWrite(4,HIGH); //Turn ON middle LED
delay(1000);
digitalWrite(3,HIGH); //Turn ON next 2 LEDs
digitalWrite(5,HIGH);
delay(1000);
digitalWrite(2,HIGH); //Turn ON next 2 LEDs
digitalWrite(6,HIGH);
delay(1000);
digitalWrite(2,LOW); //Turn OFF all LEDs
digitalWrite(3,LOW);
digitalWrite(4,LOW);
digitalWrite(5,LOW);
digitalWrite(6,LOW);
delay(1000);
}
Output
Upload the following program on Arduino after connecting the Arduino to laptop and making changes in board and port tab, you will see the 5 LED in scattering pattern
Explanation:
We start by lighting only the center LED. Then we turn on its neighbors. Then we light the end LEDs. The we switch everything off and repeat the step over.
