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.
You can use the sample programs in the following IDE libraries to do experiment on your own: _07_Sensor_LED_WS2812
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 ColorLED is used as an output pin. The Adafruit_NeoPixel library (Read more) is used to control the ColorLED.
Key Functions
Required Libraries: Adafruit_NeoPixel
Key Functions:
___.begin() - initializes the ColorLED object
___.setPixelColor(colorled_index, red_value, green_value, blue_value) - configures the color value for that colorled index, must call ___.show() for the ColorLED to actually change
colorled_index - is the index of the ColorLED to configure, first in the chain is 0, second is 1, etc
red_value - red value to set, between 0 (off) and 255 (maximum on)
green_value - green value to set, between 0 (off) and 255 (maximum on)
blue_value - blue value to set, between 0 (off) and 255 (maximum on)
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);
}
