Lesson 3: Activity 1A (Red & Green LED (Parallel)

Activity 1
Assembling Red and Green LED (Parallel) 

Materials needed:

• 1 X Arduino Board
• 1 X USB
• 1 X Laptop
• 2 X LED 
• 5 X Jumper Wires
• 2 X 330Ω resistors

Codes: 
const int ledG = 13;
const int ledR = 7;

void setup ( )
{
pinMode(ledG, OUTPUT);
pinMode(ledR, OUTPUT);
}

void loop ( )
{
digitalWrite (ledG, HIGH);
digitalWrite (ledR, LOW);
delay(1000);
digitalWrite (ledG, LOW);
digitalWrite (ledR, HIGH);
delay(1000);

}
