To carry out this simple tutorial 2, below are the items you need alongside your computer with an arduino program already installed.
Arduino UNO board
breadboard
Male-male connection cables
A 330 Ω resistor (orange, orange, brown)
one red LED
one green LED
one yellow LED
Below is the program for this tutorial:
//Declaracion de constantes
#define RED 2
#define GREEN 7
#define YELLOW 12
#define DELAYTIME 2000
void setup() {
// put your setup code here, to run once:
pinMode(RED, OUTPUT);
digitalWrite(RED, LOW);
pinMode(YELLOW, OUTPUT);
digitalWrite(YELLOW, LOW);
pinMode(GREEN, OUTPUT);
digitalWrite(GREEN, LOW);
}
void loop() {
// put your main code here, to run repeatedly:
digitalWrite (RED, HIGH);
digitalWrite (GREEN, LOW);
digitalWrite (YELLOW, LOW);
delay(DELAYTIME);
digitalWrite (RED, LOW);
digitalWrite (GREEN, HIGH);
digitalWrite (YELLOW, LOW);
delay(DELAYTIME);
digitalWrite (RED, LOW);
digitalWrite (GREEN, LOW);
digitalWrite (YELLOW, HIGH);
delay(DELAYTIME);
}
