មេរៀនទី១១៖ Blink LED

Blink LED

 

1. Objective

The objective is talk about, how to use digitalWrite in arduino to blink LED.

2. Requirement

• Arduino Uno x1
• USB Cable x1 (No need in simulation)
• Breadboard x1 (No need in simulation)
• LED x2
  
• Resistor (220Ohm or 330Ohm) x2
  
• Electronic Wire (No need in simulation) 

 

3. Build Circuit

Build circuit like Figure 1.

4. Coding

// Coding by Tann Thona (21/09/2019)

int LED = 13;
void setup() {
  // put your setup code here, to run once:
  pinMode(LED, OUTPUT);
  pinMode(12, OUTPUT);


}

void loop() {
  // put your main code here, to run repeatedly:
  digitalWrite(LED,HIGH); // OUTPUT Voltage 5V
  digitalWrite(12,0);
  delay(500);
  digitalWrite(LED, LOW);
  digitalWrite(12,1);
  delay(500);
}
