Microduino-Color led

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.

PIN3 (SIGNAL-A) Digital Output (One-wire communication)
PIN4 (SIGNAL-B) Not Connected
  • General Pin Out is the standard pin out of a Sensor / Trinket connector.
  • Sensor / Trinket's Pin Out is this specific Sensor / Trinket's wiring in relation to the General Pin Out.
  • SIGNAL-A / SIGNAL-B are signals that could be digital input, digital output, analog input or analog output. Or special signals such as serial communication (SoftwareSerial, IIC (I2C), etc) or other special signals.
  • Not Connected refers to the Pin not being used for this particular Sensor / Trinket.
  • Read more about the hub module.

Usage

Basic Functionality

The 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.

Programming

Introduction

The Buzzed Trinket is used as a output pin. Special functions on the Core module is used to generate a frequency signal to the Buzzer.

Key Functions

  • Required Libraries: None
  • Key Functions:
    • tone(pin_number, frequency) - starts generating a frequency signal on the pin, will not stop until noTone(pin_number) is called (Read more)
      • pin_number - is the pin number that the trinket is connected to
      • frequency - a frequency value to generate on the pin
    • noTone(pin_number) - stops generating a frequency on the pin (Read more)
      • pin_number - is the pin number that the trinket is connected to
    • tone(pin_number, frequency, duration) - generates a frequency signal on the pin for a set amount of time (Read more)
      • pin_number - is the pin number that the trinket is connected to
      • frequency - a frequency value to generate on the pin
      • duration - the duration in milliseconds to generate the frequency signal

Example

This is a simple example which:

  • Starts the Buzzer at a 440hz frequency.
  • Waits 1 second.
  • Turns off the Buzzer.
  • Wait 1 second.
  • Runs the Buzzer at a 294hz frequency for 2 seconds
  • Waits 5 seconds.

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);
