Overview of RGB module

I. Introduction of parameters

Two, the use of steps

1. Pin description

2. Connect the Arduino diagram

3.Arduino test program

int r=128;
int g=0;
int b=128; / / purple

void setup(a)
{
  pinMode(9,OUTPUT);
  pinMode(10,OUTPUT);
  pinMode(11,OUTPUT);
  pinMode(12,OUTPUT);
}
void loop(a)
{
  digitalWrite(12,HIGH);    / / 5 v power supply
  analogWrite(11, (255-r));
  analogWrite(10, (255-g));
  analogWrite(9, (255-b));
}
Copy the code
