Single Color LED
General Pin Out Sensor / Trinket's Pin Out
PIN1 (GND) GND
PIN2 (VCC) VCC
PIN3 (SIGNAL-A) Digital Output
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.

Usage

Basic Functionality

The LED Trinket is a simple trinket which emits light when passed with a sufficient voltage. A Core module can supply voltage to the LED Trinket.

HIGH Emits Light
LOW No Light

Programming

Introduction

The LED Trinket is used as a simple output pin. Therefore, the pinMode and digitalWrite functions will be used.

Key Functions

  • Required Libraries: None
  • Key Functions:
    • pinMode(pin_number, pin_mode) - sets the mode for the pin
      • pin_number - is the pin number that the trinket is connected to
      • pin_mode - is the mode to set the pin to. Either INPUT or OUTPUT
    • digitalWrite(pin_number) - Changes the state of the pin either to HIGH or LOW
      • pin_number - is the pin number that the trinket is connected to

Example

This is a simple example which turns on and off the LED at 1 second intervals.

Note: Important lines of code are highlighted.

//Define the pin the sensor is connected to
const int LED_PIN = 6;

void setup() {
  // put your setup code here, to run once:

  //Initial serial communication port at 9600 baud
  Serial.begin(9600);

  //Configure the pin into output mode
  pinMode(LED_PIN, OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:

  //Perform a digitalWrite with HIGH to turn on the LED
  digitalWrite(LED_PIN, HIGH);

  //Delay 1 second
  delay(1000);

  //Perform a digitalWrite with LOW to turn off the LED
  digitalWrite(LED_PIN, LOW);

  //Delay 1 second
  delay(1000);
}
