Materials​

  • 1 Franzininho DIY board
  • 1 Breadboard
  • 1 Common cathode RGB LED
  • 3 1k resistors
  • 3 Male/female jumper wires

Circuit​

On the breadboard you can assemble it as follows:

Circuit

Sketch​

// RGB with the Franzininho DIY

const int red = 0;
const int green = 1;
const int blue = 2;

void setup() {
  // configure each color pin as output:
  pinMode(red, OUTPUT);
  pinMode(green, OUTPUT);
  pinMode(blue, OUTPUT);
}

void loop() {
  // activate LED in red color:
  digitalWrite(red, HIGH);
  digitalWrite(green, LOW);
  digitalWrite(blue, LOW);
  delay(5000); // wait 5000ms

  // activate LED in green color:
  digitalWrite(red, LOW);
  digitalWrite(green, HIGH);
  digitalWrite(blue, LOW);
  delay(5000); // wait 5000ms

  // activate LED in blue color:
  digitalWrite(red, LOW);
  digitalWrite(green, LOW);
  digitalWrite(blue, HIGH);
  delay(5000); // wait 5000ms
}
