The product number of Sensor-Color LED is: MSDL11 Sensor-Color LED is full color LED, adopting single serial cascade protocol. Only one I/O port can control the RGB color of each LED on the line. If the power supply supports, it can support the cascade of as many as 1024 LEDs.

UsageBasic FunctionalityThe ColorLED is a trinket which emits different colors based on the set red, green, and blue values. A Core module can control the ColorLED to output the desired colors. Note: ColorLEDs can be connected together in a daisy chain fashion, and each ColorLED can be addressed individually using the index number. First ColorLED being 0, second ColorLED being 1, etc. ProgrammingIntroductionThe ColorLED is used as an output pin. The Adafruit_NeoPixel library (Read more) is used to control the ColorLED. Key Functions
ExampleThis is a simple example which:
Note: Important lines of code are highlighted. //Define the pin the buzzer is connected to
const int BUZZER_PIN = 6;
void setup() {
// put your setup code here, to run once:
//Initial serial communication port at 9600 baud
Serial.begin(9600);
}
void loop() {
// put your main code here, to run repeatedly:
//Start the Buzzer with a 440hz frequency
tone(BUZZER_PIN, 440);
//Wait 1 second
delay(1000);
//Turn off the Buzzer
noTone(BUZZER_PIN);
//Wait 1 second
delay(1000);
//Run the Buzzer with a 294hz frequency for 2000 milliseconds (2 seconds)
tone(BUZZER_PIN, 294, 2000);
//Wait 5 seconds
delay(5000);
