Basic Qwiic/I C Assembly For a basic Qwiic LED Stick circuit with a board like the SparkFun RedBoard Qwiic Plus all you need to do is plug the two boards together with a Qwiic cable. - Page 9 Arduino library, please check out our installation guide. The SparkFun Qwiic LED Stick Arduino Library makes controlling the LED stick as easy as sending the command with three RGB values to set the color along with a host of other functions to control the LED setLEDColor() Stick.
- Page 10 This basic example shows how to initialize the LED Stick along with controlling the LEDs on it all at once. Open the example by navigating to File > Examples > SparkFun Qwiic LED Stick Arduino Library > Example01_Blink. After opening the example, select the correct Board (in our case the SparkFun RedBoard) and Port it enumerated on.
- Page 11 LEDStick.setLEDColor(50, 50, 50); Example 3 - Single Pixels2 The third creates three arrays to set the Red, Green and Blue values for each LED. In the global class, the code creates an array for Red, Blue and Green and sets arbitrary values for each pixel. Pixel# byte redArray[10] = {214,...

LED chain. If the total current draw is outside of the limits of your chosen controller's 3.3V regulator capacity (most SparkFun Qwiic boards have a max out of 600mA@3.3V), adjust the VLED jumper to isolate the LEDs from the rest of the circuit and use a separate voltage input via the VIN PTH pin. - Page 15 SPARKFUN TECHNICAL ASSISTANCE PAGE If you don't find what you need there, the SparkFun Forums are a great place to find and ask for help.
