Goouuu-S1 ESP8266 RGB led examples

In a previous post we looked at the Goouuu-S1 ESP8266 , on the board you will have seen that there is an RGB led

The board uses the following pins for the LED

int redpin = 12; // select the pin for the red LED

int bluepin = 14; // select the pin for the blue LED

int greenpin =13; // select the pin for the green LED

Code Examples

int redpin = 12; // select the pin for the red LED
int bluepin = 14; // select the pin for the blue LED
int greenpin =13; // select the pin for the green LED
 
int val=0;
 
void setup () 
{
  pinMode (redpin, OUTPUT);
  pinMode (bluepin, OUTPUT);
  pinMode (greenpin, OUTPUT);
  Serial.begin (9600);
}
 
void loop () 
{
  for (val=255; val>0; val--)
  {
    analogWrite (redpin, val);
    analogWrite (bluepin, 255-val);
    analogWrite (greenpin, 128-val);
    delay (50);
  }
  for (val = 0; val <255; val++)
  {
    analogWrite (redpin, val);
    analogWrite (bluepin, 255-val);
    analogWrite (greenpin, 128-val);
    delay (50);
  }
  Serial.println (val, DEC);
}

 

And another example

 

int redpin = 12; // select the pin for the red LED
int bluepin = 14; // select the pin for the blue LED
int greenpin =13; // select the pin for the green LED
 
int val=0;
 
void setup () 
{
  pinMode (redpin, OUTPUT);
  pinMode (bluepin, OUTPUT);
  pinMode (greenpin, OUTPUT);
  Serial.begin (9600);
}
 
void loop () 
{
  LEDOff();
  REDOn();
  LEDOff();
  GREENOn();
  LEDOff();
  BLUEOn();
}
 
void LEDOff()
{  
  digitalWrite(redpin,HIGH);
  digitalWrite(greenpin, HIGH);
  digitalWrite(bluepin, HIGH);
  delay (500);
}
 
void REDOn()
{
  digitalWrite(redpin,LOW);
  digitalWrite(greenpin, HIGH);
  digitalWrite(bluepin, HIGH);
  delay (500);
}
 
void GREENOn()
{
  digitalWrite(redpin,HIGH);
  digitalWrite(greenpin, LOW);
  digitalWrite(bluepin, HIGH);
  delay (500);
}
 
void BLUEOn()
{
  digitalWrite(redpin,HIGH);
  digitalWrite(greenpin, HIGH);
  digitalWrite(bluepin, LOW);
  delay (500);
}

  1. Thanks! This post has been very helpful.
    But it turns out – the onboard LED is one of the very poor quality. So I will still use the separate WS2812 RGB LED.

  2. I have a Goouuu-S1 ESP8266 and can not find much information on the module.
    Would like to know what to use to program the module and how.
    The module has two switches which are not marked, what are they for?

    Thanks
